A) \[{{109}^{o}}28\]
B) \[{{100}^{o}}\]
C) \[{{180}^{o}}\]
D) \[{{120}^{o}}\]
Correct Answer: D
Solution :
Cyclic hydrocarbon in which all the carbon and hydrogen lies in same plane and carbon-carbon bond length between 1.34 A and 1.54 A is benzene. Due to resonance the \[C-C\]bond length is 1.39 \[\overset{o}{\mathop{A}}\,\] {ie, between 1.34 \[\overset{o}{\mathop{A}}\,\]and 1.54 \[\overset{o}{\mathop{A}}\,\]). Benzene is a hexagonal molecule and has \[s{{p}^{2}}\] hybridisation. So, the \[C-C\] bond angle will be \[{{120}^{o}}\] Note - Benzene is a resonance hybrid of two KekuteYou need to login to perform this action.
