Vedclass · Answer

(A) The carbon-carbon bond length in benzene is $1.39 \ \mathring{A}$.In ethane $(C_{2}H_{6})$,the $C-C$ single bond length is $1.54 \ \mathring{A}$.In ethene $(C_{2}H_{4})$,the $C=C$ double bond length is $1.34 \ \mathring{A}$.Since $1.34 \ \mathring{A} < 1.39 \ \mathring{A} < 1.54 \ \mathring{A}$,the bond length in benzene lies between that of $C_{2}H_{6}$ and $C_{2}H_{4}$.
