  • Question 1
    1 / -0

    Which of the following products is obtained by the oxidation of propionaldehyde?

    Solution

     

  • Question 2
    1 / -0

    Acetaldehyde can not exhibit which of the following reaction?

    Solution

    Acetaldehyde cannot exhibit Lucas's test. 

    This test only performs to differentiate between primary and secondary and tertiary alcohol. Luca's reagent is a solution of ZnCl2​ (Anhydrous) and HCl acid. Acetaldehyde does not undergo reaction with Luca's reagent. 

     

  • Question 3
    1 / -0

    The compound obtained by the reduction of propionaldehyde by amalgamated zinc and concentrated HCl is :

    Solution

    This reaction is called clemmenson's reduction 

     

  • Question 4
    1 / -0

    Trichloroacetaldehyde, CCl3​CHO reacts with chlorobenzene in presence of sulphuric acid and produces:

    Solution

    From the above reaction trichloroacetaldehyde CCl3​CHO reacts with chlorobenzene in presence of Sulphuric acid produces DDT

     

  • Question 5
    1 / -0

    Benzyl alcohol is obtained from benzaldehyde by

    Solution

     

  • Question 6
    1 / -0

    In a cannizaro reaction, the intermediate that will be the best hydride donor is:

    Solution

    In a Cannizaro reaction, the intermediate that will be the best hydride donor is represented by option A. It is obtained when hydroxide ion attacks a molecule of benzaldehyde. The intermediates shown in options B, C and D cannot be formed in this reaction.

     

  • Question 7
    1 / -0

    Base catalysed aldol condensation occurs with:

    Solution

    Benzaldehyde,  2, 2-dimethylpropanal and formaldehyde do not contain alpha hydrogen atom. Hence, they undergo cannizaro reaction on treatment with base.

    2-methyl propanal contains an alpha carbon atom. Hence, on treatment with base, it undergoes aldol condensation reaction.

     

  • Question 8
    1 / -0

    Which of the aldehydes is most reactive ?

    Solution

    Among Carbonyl Compounds , reactivity decrease with increase in alkyl groups as alkyl groups ( +I effect ) decrease positive character on C-atom . Thus , the correct order of reactivity is 

    HCHO > CH3​CHO > C6​H5​CHO 

     

  • Question 9
    1 / -0

    Which of the following reagents reacts differntly with HCHO, CH3CHO and CH3COCH3

    Solution

     

  • Question 10
    1 / -0

    Consider the reaction:

    RCHO + NH2NH2 → RCH = N - NH2

    What sort of reaction is it?

    Solution
