  • Question 1
    1 / -0

    The order of susceptibility of nucleophilic attack on aldehydes follows the order

    Solution

    As the alkyl group increases, carbonyl becomes a weak electrophile and the reactivity becomes low. So, the order is 1∘>2∘>3∘

     

  • Question 2
    1 / -0

    Which of the follwoing compounds will show positive silver mirror test?

    Solution

    All aldehydes, formic acid give this test. α-hydroxy ketone also give this test because of H-CO- group presence

     

  • Question 3
    1 / -0

    C2​H5​CHO and (CH3​)2​CO can be distinguished by testing with

    Solution

     

  • Question 4
    1 / -0

    Which will form two oximes with NH2​OH?

    Solution

    Two isomeric oximes are formed when an aldehyde (other than formaldehyde) or a non- symmetrical ketone reacts with hydroxylamine as shown above.

     

  • Question 5
    1 / -0

    Clemmensen reduction of a ketone is carried out in the presence of which of the following reagent?

    Solution

    Clemmensen reduction of a ketone is carried out in the presence of Zn−Hg with HCl. This reduction converts carbonyl group to methylene group. It is suitable for compounds that are sensitive to alkali.

     

  • Question 6
    1 / -0

    When sodium formate is heated it gives

    Solution

     

  • Question 7
    1 / -0

    Which of the following is used as hypnotic or sedative?

    Solution

    Paraldehyde is the cyclic trimer of acetaldehyde molecule. It is a hypnotic and sedative with anticonvulsant effects.

     

  • Question 8
    1 / -0

    3-Hydroxybutanal is formed when (X) reacts with (Y) in dilute (Z) solution. What are X, Y and Z

    Solution

     

  • Question 9
    1 / -0

    Which one of the following undergoes reaction with 50% sodium hydroxide solution to give the corresponding alcohol and acid?

    Solution

    Benzaldehyde will undergo Cannizzaro reaction on treatment with 50% NaOH to produce benzyl alcohol and benzoic acid as it does not contain α-hydrogen

     

  • Question 10
    1 / -0

    Acetaldehyde is produced from the following in the presence of aqueous KMnO4 solution

    Solution
