MCQ
Reactivity towards nucleophilic addition reaction of
$(I) HCHO$,
$(II)$ $C{H_3}CHO$,
$(III)$ $C{H_3}COC{H_3}$ is
- A$II > III > I$
- B$III > II > I$
- ✓$I > II > III$
- D$I > II < III$
✓
Answer
Correct option: C.
$I > II > III$
c
(c) Carbonyl carbon become more reactive toward nucleophilic addition by increasing the $+I$ effect of alkyl group so the reactivity order is as
$\mathop {HCHO}\limits_{\text{I}} > \mathop {C{H_3}CHO}\limits_{{\text{II}}} > \mathop {C{H_3}COC{H_3}}\limits_{{\text{IIII}}} $
