Arrange the following compounds in increasing order of their reactivity in nucleophilic addition reactions. Ethanal (I), Propanal (II), Propanone (III), Butanone (IV).
A) II < I < III < IV
B) III < II < I < IV
C) I < II < III < IV
D) IV < III < II < I
Correct Answer:
D
Solution :
As the steric hindrance increases, the reactivity decreases, accordingly, so the order of reactivity is I > II > III > IV Hence, the correct option is [d].
