A) \[{{109}^{o}}28\]
B) \[{{100}^{o}}\]
C) \[{{180}^{o}}\]
D) \[{{120}^{o}}\]
Correct Answer: D
Solution :
Cyclic hydrocarbon, with carbon-carbon bond length between \[1.34\overset{\text{o}}{\mathop{\text{A}}}\,\] and \[1.54\overset{\text{o}}{\mathop{\text{A}}}\,,\] is benzene in which due to resonance, C?C bond length is \[1.39\overset{\text{o}}{\mathop{\text{A}}}\,\] (i.e, between \[1.34\overset{\text{o}}{\mathop{\text{A}}}\,-1.54\overset{\text{o}}{\mathop{\text{A}}}\,\]). Benzene is a hexagonal molecule with bond-angle equal to \[\text{12}{{\text{0}}^{\text{o}}}.\]You need to login to perform this action.
