A) Tautomerism
B) Inductive effect
C) Resonance
D) Isomerism
Correct Answer: C
Solution :
All the bonds \[(C-C)\] are equal in benzene. The \[C-C\] bond length is \[1.39\text{{ }\!\!\mathrm{\AA}\!\!\text{ }}\] which is in between \[C-C\] bond \[\underset{\begin{matrix} {} \\ \begin{smallmatrix} \text{1, 2, 3-Trimethyl} \\ \text{benzene} \end{smallmatrix} \\ \end{matrix}}{\mathop{\begin{matrix} C{{H}_{3}} \\ {} \\ {} \\ \end{matrix}\,\,\,\,}}\,\] and \[C=C\] \[(1.34\text{{ }\!\!\mathrm{\AA}\!\!\text{ }})\].You need to login to perform this action.
