The order of reactivities of methyl halide in the formation of Grignard reagent is

A

`CH_(3)I gt CH_(3)Br gt CH_(3)Cl`

B

`CH_(3)Cl gt CH_(3)Br gt CH_(3)I`

C

`CH_(3)Br gt CH_(3)Cl gt CH_(3)I `

D

`CH_(3)Br gt CH_(3)I gt CH_(3)CI`

Text Solution

Verified by Experts

The correct Answer is:
A
Among alkyl halides, iodides are least stable, hence these from Grignard reagent easily. Thus, the correct order of reactivity in formation of Grignard reagent is
`CH_(3)l gt CH_(3)Br gt CH_(3)Cl`
