The carbon-carbon bond length in benzene is :

Options

A. same s in `C_(2)H_(4)`
B. in between `C_(2)H_(6)` and `C_(2)_(2)`
C. in between `C_(2)H_(4)` and `C_(2)H_(2)`
D. in between `C_(2)H_(6)` and `C_(2)H_(4)`

Answer

D

Explanation

In benzene, due to delocalisation of `pi` electrons, all the C-C bond lengths are equal as each C-C bond has some double bond character and thus the bond length is between single and double bond i.e., between `C_(2)H_(6)` and `C_(2)H_(4)`.
