Options

A. `154 p m`
B. `120 p m`
C. `134 p m`
D. `142 p m`

Answer

C

Explanation

The order of carbon-carbon bond distance is
`underset((154 p m))underset("ethane")underset(1n)(C-C) gt underset((134 p m))underset("ethene")underset(1n)(C-C) gt underset((120 p m))underset("ethyne")underset(1n)(C-C)`
