The correct order of reactivity of PhMgBr with following compounds will be.
(C6H5)2CO, CH3 – CH = O , (CH3)2 C = O
(1) (2) (3)
A
1 > 2 > 3
B
2 > 3 > 1
C
3 > 2 > 1
D
1 > 3 > 2
Answer
2 > 3 > 1
Explanation
Solution
As the positive charge decreases and steric hinderance increases on carbonyl group the rate of nucleophilic addition reaction decreases.
