    In IR spectra the stretching is due to

    • A.

      Change in symmetry of the compound

    • B.

      Change in bond angle of the compound

    • C.

      Change in bond strength of the compound

    • D.

      Change in bond lenght of the compound

    Correct Answer
    D. Change in bond lenght of the compound
    Explanation
    In IR spectra, the stretching is due to the change in bond length of the compound. When a molecule absorbs infrared radiation, it causes the bonds between atoms to vibrate. This vibration results in a change in the bond length, which can be detected in the IR spectrum. The stretching frequency is directly related to the strength and stiffness of the bond, and it provides information about the types of bonds present in the compound. Therefore, the correct answer is "change in bond length of the compound".

    Correct Answer
    C. 1.8 x 10-16 mol/L
    Explanation
    The dissociation constant of water is a measure of how much water molecules dissociate into hydrogen ions (H+) and hydroxide ions (OH-) in a given solution. The dissociation constant is typically represented by the symbol Kw and is equal to the product of the concentrations of H+ and OH- ions in the solution. The correct answer of 1.8 x 10-16 mol/L indicates a very low dissociation constant, suggesting that water molecules do not dissociate significantly in the given solution.

    Increase in S – character IR causes absorption to move

    • A.

      Left

    • B.

      Right

    • C.

      Constant

    • D.

      None

    Correct Answer
    A. Left
    Explanation
    An increase in the S-character of an atom in a molecule causes the absorption to shift towards the left. This is because an increase in S-character leads to a greater electronegativity and a stronger pull on the electrons, causing them to be more tightly held by the atom. As a result, the absorption of light by the molecule occurs at a higher energy level, which corresponds to a shorter wavelength and a shift towards the left on the absorption spectrum.

    • C.

      8.46

    • D.

      8.35

    Correct Answer
    B. 8.1
    Explanation
    Fastest machine makes ‘T’ toys in 8 hours.
    Slowest machine makes ‘T’ toys in 9 hours
    We do not know how much time the other 2 machines take. There are 2 extreme possibilities. The other 2
    machines can be neither faster than the fastest machine nor can they be slower than the slowest machine.
    \ If the other 2 are as fast as the fastest machine,
    Total time taken to make ‘T’ toys each = 8 + 8 + 8 + 9 hours = 33 hours
    \ Average Time = 33 ´ 1/4 = 8.25 hours
    If the other 2 are as slow as the slowest machine,
    Total time taken to make ‘T’ toys each = 8 + 9 + 9 + 9 = 35 hours
    \ Average time = 35/4 = 8.75 hours
    \ Average has to range between 8.25 and 8.75.
    Option 2, 8.1 hours, is not possible.
    Hence B

      Flucytosine

    • D.

      acriflavine

    Correct Answer
    C. Flucytosine
    Explanation
    Flucytosine is the correct answer because it acts by causing frameshift mutations. Frameshift mutations occur when nucleotides are inserted or deleted in the DNA sequence, causing a shift in the reading frame. Flucytosine is an antifungal agent that is converted into 5-fluorouracil inside fungal cells. This conversion disrupts protein synthesis by causing frameshift mutations, ultimately leading to cell death. Therefore, flucytosine acts by inducing frameshift mutations in the fungal DNA.

    • D.

      Formation of Hcl when cl is added to water of Hydrogen

    Correct Answer
    A. Formation of Hcl when cl is added to water
    Explanation
    The correct answer is the formation of HCl when Cl is added to water. When chlorine (Cl) is added to water, it reacts with the water molecules to form hydrochloric acid (HCl). This reaction helps in disinfecting the water by killing bacteria and other harmful microorganisms present in it.

    DOC for lithium induced nephrogenic diabetes insipidus?

    • A.

      Lypressin

    • B.

      Thiazides

    • C.

      Furosemide

    • D.

      Amiloride

    Correct Answer
    D. Amiloride
    Explanation
    Amiloride is the correct answer for the DOC (drug of choice) for lithium-induced nephrogenic diabetes insipidus. This condition is caused by the use of lithium, a medication commonly used to treat bipolar disorder. Amiloride is a potassium-sparing diuretic that works by blocking the epithelial sodium channels in the distal tubules of the kidneys, thereby reducing the excretion of water. It is effective in treating lithium-induced nephrogenic diabetes insipidus by reducing the excessive urine output associated with the condition. Thiazides and furosemide are not commonly used for this condition, and lypressin is a synthetic form of vasopressin that is not typically used as the first-line treatment for lithium-induced nephrogenic diabetes insipidus.

    Artificial honey is detected by reaction with ?

    • A.

      Resorcinol in HCl

    • B.

      Ruthenium red

    • C.

      H2O2 & benzinide in alcohol

    • D.

      NaOH

    Correct Answer
    A. Resorcinol in HCl
    Explanation
    Resorcinol in HCl is used to detect artificial honey. Resorcinol is a chemical compound that reacts with certain substances present in artificial honey, causing a color change or other observable reactions. When combined with hydrochloric acid (HCl), the reaction becomes more specific and can accurately identify the presence of artificial honey. This method is commonly used in food testing laboratories to distinguish between natural and artificial honey.

    Which of the following statement is true:

    • A.

      Nafcillin is beta-lactamase resistant antibiotic

    • B.

      Cefazolin is second generation cephalosporin

    • C.

      Tazobactam is used in gonorrhea mainly

    • D.

      Penicillin G is contraindicated in infections caused by spirochetes

    Correct Answer
    A. Nafcillin is beta-lactamase resistant antibiotic
    Explanation
    Nafcillin is a beta-lactamase resistant antibiotic because it belongs to the class of penicillinase-resistant penicillins. This means that it is effective against bacteria that produce beta-lactamase enzymes, which can break down other penicillin antibiotics and render them ineffective. Nafcillin has a side chain that protects it from beta-lactamase enzymes, allowing it to maintain its antimicrobial activity against these resistant bacteria.

    Cabohydrate undergo oxidative clavage by

    • A.

      Periodic acid

    • B.

      Perchloric acid

    • C.

      Perbromic acid

    • D.

      All of above

    Correct Answer
    A. Periodic acid
    Explanation
    Carbohydrates undergo oxidative cleavage by periodic acid. Periodic acid is a strong oxidizing agent that can cleave the carbon-carbon bonds in carbohydrates, resulting in the formation of aldehydes or ketones. This reaction is commonly used in carbohydrate chemistry to selectively cleave glycols and diols. Perchloric acid and perbromic acid are not commonly used for this purpose and may not have the same selectivity and efficiency as periodic acid. Therefore, the correct answer is periodic acid.

    • A.

      Aromaticity

    • B.

      Aliphaticdly

    • C.

      Both a & b

    • D.

      Functional group

    Correct Answer
    C. Both a & b
    Explanation
    In the IR spec of an organic compound, the hydrogen stretching region is usually first investigated to determine both aromaticity and aliphaticity. The presence of certain characteristic peaks in this region can provide information about the type of bonding present in the compound, whether it is aromatic or aliphatic. Aromatic compounds typically exhibit a strong, sharp peak in the hydrogen stretching region, while aliphatic compounds show a broader, less intense peak. Therefore, by analyzing the peaks in this region, one can determine whether the compound is aromatic or aliphatic, or possibly both.
