Which of the following compounds is most reactive towards nucleophilic addition reactions?

Options

A. `CH_3-overset(O)overset(||)C-H`
B. `CH_3-overset(O)overset(||)C-CH_3`
C.
D.

Answer

A

Explanation

Reactivity of carbonyl compounds can be decided by two factors.
(i) Steric factor Lesser the steric factor greater will be its reactivity.
(ii) Electronic factor Greater the number of alkyl group lesser will be its electrophilicity.
Hence, `CH_3 - CHO` is most reactive towards nucleophilic addition reaction.
