Aldehydes and Ketones - Result Question 73
####84. Arrange the following in order of their increasing reactivity towards $HCN$ :
$CH _3 CHO, CH _3 COCH _3, HCHO, C _2 H _5 COCH _3$
(1985, 1M)
Show Answer
Solution:
- Steric hindrance at carbonyl carbon determine the reactivity towards nucleophilic addition reaction. Greater the steric hindrance, smaller the reactivity.
$C _2 H _5 COCH _3<CH _3 COCH _3<CH _3 CHO<HCHO$
