The order of reactivity of phenyl magnesium bromide with the following compounds is
A.(II) > (III) > (I)
B.(I) > (III) > (II)
C.(II) > (I) > (III)✓ Correct
D.All react with the same rate
Explanation
The order of the reactivity of the phenyl magnesium bromide that is PhMgBr with the following compounds will be represented as II > I > III because as the number of the alkyl group increase or we can say that the size of the alkyl group increases the steric crowding also increases and the ease of the nucleophilic attack also decreases. Hence, the correct answer is option (c)
