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 \[{{C}_{2}}{{H}_{2}}\]
Correct Answer: A
Solution :
The carbon-carbon bond length in benzene \[(1.39\text{ }\overset{o}{\mathop{A}}\,)\] is between that of \[C-C\,\,(1.54\overset{o}{\mathop{A}}\,)\]and \[C=C\,\,(1.34\overset{o}{\mathop{A}}\,)\] ie, in between that of \[{{C}_{2}}{{H}_{6}}\] and \[{{C}_{2}}{{H}_{4}}\].
