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

  Both Statement I and Statement II are true.
• B

  Both Statement I and Statement II are false.
• C

  Statement I is true but Statement II is false.
• Correct answer
  D

  Statement I is false but Statement II is true.

Solution

- In an organic compound when inductive and electromeric effects operate in opposite directions, the electromeric effect predominates.
In alkylarene, $s p^3$ hybridized $\mathrm{C}-\mathrm{H}$ bonds are present the carbon of which is directly bonded to $s p^2$ carbon atoms so, hyperconjugation effect is observed in o-xylene.

Hence, the correct answer is option: 'D'.
