Nucleophilic addition reaction will be most favoured in which among the following compounds?
Nucleophilic addition reaction will be most favoured in which among the following compounds?
$\mathrm{CH}_3 \mathrm{CH}_2 \mathrm{CHO}$
$\mathrm{CH}_3 \mathrm{CHO}$
Solution
(i) Aldehyde and ketone which are less hindered at carboxyl carbon show nucleophilic addition reaction at high rate.
(ii) Presence of electron donating groups at carbonyl carbon decrease the rate.
$\therefore$ Nucleophilic addition reaction will be most favored in $\mathrm{CH}_3 \mathrm{CHO}$.
