Given below are two statements: Statement I: In O₂ N - C₆ H₄ - CH^ - C₆ H₄ - OCH₃ , the carbocation is stabilised by +R effect of -OCH₃ group. Statement II: In O₂ N - C₆ H₄ - CH^ - C₆ H₄ - OCH₃ , the carbanion is stabilised by -R effect of -NO₂ group. In the light of the above statements, choose the correct answer from the options given below:
Options
- ABoth Statement I and Statement II are true
- BBoth Statement I and Statement II are false
- CStatement I is true but Statement II is false
- DStatement I is false but Statement II is true
Correct answer
A. Both Statement I and Statement II are true
Step-by-step solution
Statement I is true because the -OCH₃ group is an electron-donating group. It donates electron density through resonance ( +R effect), which delocalizes the positive charge of the carbocation and stabilizes it. Statement II is true because the -NO₂ group is a strong electron-withdrawing group. It withdraws electron density through resonance ( -R effect), which delocalizes the negative charge of the carbanion and stabilizes it. Therefore, both Statement I and Statement II are true. Answer: Both Statement I and State
