The correct order of increasing bond length of C-H, C-O, C - C and C = C is

A

`I lt II lt III, IV`

B

`I lt IV lt II lt III`

C

`IV lt III lt II lt I`

D

`III lt IV lt II lt I`

Text Solution

Verified by Experts

The correct Answer is:
B
`C-C` is the longest of all and `C-O` is longer than `C = C`.
` C – H` bond is shortest because of small size of H.
Double bond is smaller than single bond because of more s character.
`C-H lt C=C lt C -O lt C -C`
