Q. The carbon-carbon bond length in benzene is
A) In between $C_{2}H_{6}\ and\ C_{2}H_{4}$
B) Same as in $C_{2}H_{4}$
C) In between $C_{2}H_{6}\ and\ C_{2}H_{2}$
D) In between $C_{2}H_{4}\ and\ C_{2}H_{2}$
Explanation
(a)
The carbon-carbon bond length in benzene $(1.39\ \mathring{\mathrm{A}})$ in between that of $C - C(1.54\ \mathring{\mathrm{A}})and\ C = C(1.34\ \mathring{\mathrm{A}})$ $i.e.,$ in between that of $C_{2}H_{6}\ and\ C_{2}H_{4}$.
