  • 2. 

    The product formed in Wolff-Kishner Reduction ?

    • Sugar

    • Alkane

    • Ester

    • Amides

    Correct Answer
    A. Alkane
    Explanation
    In Wolff-Kishner reduction, a carbonyl compound is converted into an alkane. This reaction involves the use of hydrazine (N2H4) and a strong base, such as KOH or NaOH, to generate a hydrazone intermediate. The hydrazone is then treated with a strong base and heated, causing the carbon-nitrogen double bond to break and resulting in the formation of an alkane. Therefore, the correct answer is Alkane.

    The reagent used in Clemmensen Reduction is ?

    • Sucrose/Ethanol

    • LiAlH4

    • Zinc - Amalgam (Zn-Hg)

    • None of the above

    Correct Answer
    A. Zinc - Amalgam (Zn-Hg)
    Explanation
    The correct answer is Zinc - Amalgam (Zn-Hg). Clemmensen Reduction is a chemical reaction used to convert carbonyl compounds, such as ketones and aldehydes, into their corresponding alkanes. In this reaction, zinc is combined with mercury to form a zinc amalgam, which acts as the reducing agent. The amalgam reduces the carbonyl group to an alkyl group, resulting in the formation of an alkane. Sucrose/Ethanol and LiAlH4 are not reagents used in Clemmensen Reduction.

    The acetylsalicylic acid is also known as

    • Salicylic acid

    • Aspirin

    • Phenolic acid

    • All the above

    Correct Answer
    A. Aspirin
    Explanation
    Acetylsalicylic acid is commonly known as aspirin. It is a medication used to treat pain, fever, and inflammation. While salicylic acid is a related compound, it is not the same as acetylsalicylic acid. Phenolic acid is a general term for a class of compounds that have a phenol group attached to a carboxylic acid group, but it is not specifically referring to acetylsalicylic acid. Therefore, the correct answer is aspirin.

    Wolff- Kishner Reagent is

    • Hydrazine

    • Zn-Hg

    • KMnO4

    • Barium Chloride

    Correct Answer
    A. Hydrazine
    Explanation
    The correct answer is Hydrazine. Hydrazine is a powerful reducing agent commonly used in the Wolff-Kishner reduction reaction. This reaction is used to convert carbonyl compounds, such as ketones and aldehydes, into their corresponding hydrocarbons. Hydrazine reacts with the carbonyl compound to form a hydrazone intermediate, which is then treated with a strong base to eliminate nitrogen gas and yield the reduced product. This reaction is widely used in organic synthesis and provides a convenient method for the conversion of carbonyl compounds into saturated hydrocarbons.

    The reducing agent used in Birch Reduction is ?

    • Liq.NH3 / Na

    • LiAlH4

    • KMnO4

    • Starch

    Correct Answer
    A. Liq.NH3 / Na
    Explanation
    The reducing agent used in Birch Reduction is liquid ammonia (Liq.NH3) combined with sodium (Na). This combination creates a strong reducing environment, allowing for the reduction of certain organic compounds. LiAlH4 is a common reducing agent, but it is not used in Birch Reduction. KMnO4 is an oxidizing agent, not a reducing agent. Starch is not a reducing agent and is not involved in the Birch Reduction process.

    The intermediate involved in Reimer-Tiemann Reaction is

    • Carbene

    • Carbocation

    • Carbanion

    • Nitronium ion

    Correct Answer
    A. Carbene
    Explanation
    In the Reimer-Tiemann Reaction, the intermediate involved is a carbene. A carbene is a molecule that contains a carbon atom with only two bonds and an unshared pair of electrons. This intermediate is formed when a chloroform molecule reacts with a strong base, such as hydroxide ion. The carbene then reacts with an aromatic compound, resulting in the formation of a new carbon-carbon bond. This reaction is commonly used to introduce a formyl group (-CHO) into aromatic compounds.

    The Reagent used in wittig reaction is

    • Acetaldehyde

    • Hydrazine

    • Phosphorus

    • Phosphorus Ylide

    Correct Answer
    A. Phosphorus Ylide
    Explanation
    Phosphorus ylide is the correct answer for the reagent used in the Wittig reaction. The Wittig reaction is a chemical reaction that involves the formation of a carbon-carbon double bond using a phosphorus ylide and a carbonyl compound. Phosphorus ylides are compounds that contain a positively charged phosphorus atom and a negatively charged carbon atom. They are capable of reacting with carbonyl compounds to form an alkene product. Therefore, in the context of the Wittig reaction, phosphorus ylide is the reagent that is used.

    Cannizaro reaction takes place in ?

    • Acetaldehyde

    • Charcoal

    • Acetone

    • Formaldehyde

    Correct Answer
    A. Formaldehyde
    Explanation
    The Cannizaro reaction is a redox reaction that occurs in formaldehyde. It involves the oxidation of one molecule of formaldehyde to formic acid and the reduction of another molecule of formaldehyde to yield methanol. This reaction is typically catalyzed by a strong base, such as hydroxide ion. The reaction does not occur in acetaldehyde, charcoal, or acetone.

  • 10. 

    The process done in Wittig reaction is?

    • Olefination

    • Methylation

    • Hydrolysis

    • Redox reaction

    Correct Answer
    A. Olefination
    Explanation
    The process done in Wittig reaction is olefination. The Wittig reaction involves the formation of a carbon-carbon double bond (olefin) through the reaction between a phosphonium ylide and a carbonyl compound. This reaction is widely used in organic synthesis to selectively introduce double bonds into molecules.
