    Which of the following compounds is readily to dissolve in water?  - ProProfs

    Which of the following compounds is readily to dissolve in water? 

    • Pentane

    • Pentanol

    • Pentanoic acid

    • Sodium pentanoate

    • Penthouse

    Correct Answer
    A. Sodium pentanoate
    Explanation
    d is very soluble because it's a salt. b and c are slightly soluble.

    Choose the correct sequence of the following compounds in the order of decreasing acidity.(a) water(b) propanoic acid(c) propylamine(d) HCl - ProProfs

    Choose the correct sequence of the following compounds in the order of decreasing acidity.(a) water(b) propanoic acid(c) propylamine(d) HCl

    • A > b > c > d

    • D > c > b > a

    • D > b > a > c

    • D > b > c > a

    • None of the above is correct

    Correct Answer
    A. D > b > a > c
    Explanation
    HCl is of course the strongest acid. Water is neutral, but more "acidic" than the propylamine base.

    Which of the following groups is likely to form a homogeneous solution?   - ProProfs

    Which of the following groups is likely to form a homogeneous solution?  

    • Water, salt, baby oil

    • Water, ethanol, gasoline

    • Ethanol, gasoline, NaOH

    • Cooking oil, gasoline, paraffin

    • None of the above

    Correct Answer
    A. Cooking oil, gasoline, paraffin
    Explanation
    All the three components in Group D are hydrocarbons and thus miscible.

    Rate this question:

  • 5. 
    Which of the following pairs has the highest and lowest boiling points (in any order)?  - ProProfs

    Which of the following pairs has the highest and lowest boiling points (in any order)? 

    • Water & NaOH

    • NaOH & MeOH

    • MeOH & Water

    • Water & EtOH

    • EtOH & MeOH

    Correct Answer
    A. NaOH & MeOH
    Explanation
    NaOH is a solid and has the highest BP. MeOH has the lowest BP. Water has a higher BP than all three alcohols.

    Rate this question:

  • 6. 
    Which of the following compounds is likely to have the lowest flash point?   - ProProfs

    Which of the following compounds is likely to have the lowest flash point?  

    • Gasoline

    • Cooking oil

    • Pentane

    • Rubbing alcohol

    • Carbon dioxide

    Correct Answer
    A. Pentane
    Explanation
    Gasoline (C8-C12) is extremely flammable; but pentane has an even lower BP, and thus the FP. Carbon dioxide is a gas but not flammable.
