Arrange the following bonds according to their averge bond energies in descending order:
`C - Cl,C - Br ,C-R ,C-I`

A

`C-I gt C-Br gt C-Cl gt C-F`

B

`C-Br gt C-I gt C - Cl gt C-F`

C

`C-F gt C-Cl gt C - Br gt C-I`

D

`C-Cl gt C-Br gt C-I gt C-F`

Text Solution

Verified by Experts

The correct Answer is:
C
Greater the bond length, lesser is the bond energy.
Order of bond length: `C-I gt C-Br gt C-Cl gt C-F`
Order of bond energy : `C-F gt C-Cl gt C-Br gt C-I`
