Inductive and electromeric effects; hyperconjugation
-
Given below are two statements: Statement I: In an organic compound, when inductive and electromeric effects operate in opposite directions, the inductive effect predominates. Statement II: Hyperconjugation is observed in o-xylene. In the light of the above statements, choose the correct answer from the options given below:A Statement-I is true but Statement-II is false.B Statement-I is false but Statement-II is true.C Both Statement-I and Statement-II are true.D Both Statement-I and Statement-II are false.When inductive and electromeric effects act in opposite directions in an organic compound, the electromeric effect predominates over the inductive effect, not the other way around — so Statement I is false. Hyperconjugation, involving the overlap of a C–H sigma bond with an adjacent pi system, is indeed observed in o-xylene (through its methyl group's C–H bonds interacting with the aromatic ring) — Statement II is true.
