The correct order of reactivity of CH3MgBr with following compounds will be :
CH3–CHO, HCHO, Ph–CHO
A
2 > 1 > 4 > 3
B
4 > 3 > 1 > 2
C
2 > 1 > 3 > 4
D
1 > 3 > 2 > 4
Answer
2 > 1 > 3 > 4
Explanation
Solution
As steric hinderance increases on carbonyl group the rate of nucleophilic addition reaction decreases.
