Question

Arrange the following carbonyl compounds in decreasing order of their reactivity in nucleophilic addition reaction:

• A. $ii>iii>i>iv$
• B. $ii>i>iv>iii$
• C. $iii>ii>i>iv$
• D. $iii>i>iv>ii$

Answer 1

Answer: (B)

The order of reactivity of carbonyl in nucleophilic addition reaction depends on electron deficiency on carbonyl carbon i.e. EWG group in the compound.

So, the order will be (ii) > (i) > (iv) >(iii)
