Arrange the following in the increasing order of their property indicated :(a)Ethanal, Propanone, Propanal, Butanone (reactivity towards nucleophilic addition)(b)$\displaystyle 4$-Nitrobenzoic acid, benzoic acid, $\displaystyle 3,4$-Dinitrobenzoic acid, $\displaystyle 4$-Methoxy benzoic acid (Acid strength)
Arrange the following in the increasing order of their property indicated :
(a)
Ethanal, Propanone, Propanal, Butanone (reactivity towards nucleophilic addition)
(b)
$\displaystyle 4$-Nitrobenzoic acid, benzoic acid, $\displaystyle 3,4$-Dinitrobenzoic acid, $\displaystyle 4$-Methoxy benzoic acid (Acid strength)
Marking-scheme solution
(a) Butanone < Propanone < Propanal < Ethanal
(b) $\displaystyle 4$-Methoxybenzoic acid < Benzoic acid < $\displaystyle 4$-Nitrobenzoic acid < $\displaystyle 3,4$-Dinitrobenzoic acid.
