Given below are two statements: Statement I: In O_2 N-C_6 H_4-CH^ -C_6 H_4-OCH_3, the carbocation is stabilised by +R effect of -OCH_3 group. Statement II: In O_2 N-C_6 H_4-CH^ -C_6 H_4-OCH_3, the carbanion is stabilised by -R effect of -NO_2 group. 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
Statement I is true because the -OCH_3 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 -NO_2 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 Statement II are true
