Arrange the following in the increasing order of their property indicated:
(a) Ethanal, Propanone, Propanal, Butanone (reactivity towards nucleophilic addition)
(b) 4-Nitrobenzoic acid, benzoic acid, 3,4-Dinitrobenzoic acid, 4-Methoxy benzoic acid (Acid strength)
(a) Ethanal, Propanone, Propanal, Butanone (reactivity towards nucleophilic addition)
(b) 4-Nitrobenzoic acid, benzoic acid, 3,4-Dinitrobenzoic acid, 4-Methoxy benzoic acid (Acid strength)
Solution:
(a) The increasing order towards nucleophilic addition of the following compounds is
Butanone Propanone Propanal Ethanal (Due to effect).
(b) The increasing order of acidic strength of the following compounds is
4-methoxy benzoic acid < benzoic acid < 4-nitrobenzoic acid < 3,4-dinitrobenzoic acid. (Due to presence of electron withdrawing group).
Butanone Propanone Propanal Ethanal (Due to effect).
(b) The increasing order of acidic strength of the following compounds is
4-methoxy benzoic acid < benzoic acid < 4-nitrobenzoic acid < 3,4-dinitrobenzoic acid. (Due to presence of electron withdrawing group).
