Reactivity order of halides of dehydrohalogenation is

A

`R-F gt R-Cl gt R-Br gt R-I`

B

`R-I gt R-Br gt R-Cl gt R-F`

C

`R-I gt R-Cl gt R-Br gt R-F`

D

`R-F gt R-I gt R-Br gt R-Cl`

Text Solution

Verified by Experts

The correct Answer is:
B
F, Cl, Br and l are the elements of VII A group. In a group, atomic radii increases from top to bottom and the bond dissociation energy decreases as
`R-F gt R-Cl gt R-Br gt R-l.`
