For the compounds CH(3)Cl, CH(3)Br, CH(3...

For the compounds `CH_(3)Cl, CH_(3)Br, CH_(3)I` and `CH_3F`, the correct order of increasing C-halogen bond length is:

A

`CH_(3)F lt CH_(3)Cl lt CH_(3)Br lt CH_(3)I`

B

`CH_(3)F lt CH_(3)Br lt CH_(3)Cl lt CH_(3)I`

C

`CH_(3)F lt CH_(3)I lt CH_(3)Br lt CH_(3)Cl`

D

`CH_(3)Cl lt CH_(3)Br lt CH_(3)F lt CH_(3)I`

Text Solution

Verified by Experts

The correct Answer is:
A
Bond length of carbon halogen bond depends on the size of halogen atom. Larger the size of halogen atom, larger is the bond length.
`F lt Cl lt Br lt I` - Atomic size
`H_(3)C - F lt CH_(3) - Cl lt CH_(3) - Br lt CH_(3) - I` - Bond length
