State True or False for the following statements regarding the $-NO_2$ group in nitrobenzene:
$(i)$ In resonance,it acts as an electron-donating group,and in the inductive effect,it acts as an electron-attracting group.
$(ii)$ It acts as an electron-donating group in both resonance and the inductive effect.
$(iii)$ It acts as an electron-attracting group in both resonance and the inductive effect.
$(iv)$ It acts as an electron-attracting group in resonance and an electron-donating group in the inductive effect.
$(i)$ In resonance,it acts as an electron-donating group,and in the inductive effect,it acts as an electron-attracting group.
$(ii)$ It acts as an electron-donating group in both resonance and the inductive effect.
$(iii)$ It acts as an electron-attracting group in both resonance and the inductive effect.
$(iv)$ It acts as an electron-attracting group in resonance and an electron-donating group in the inductive effect.
(C) The $-NO_2$ group is a strong electron-withdrawing group due to both its resonance effect ($-M$ effect) and its inductive effect ($-I$ effect).
$(i)$ False: It is electron-attracting in both effects.
$(ii)$ False: It is electron-attracting in both effects.
$(iii)$ True: It withdraws electrons via resonance $(-M)$ and induction $(-I)$.
$(iv)$ False: It is electron-attracting in both effects.
Final answer: $(i-F, ii-F, iii-T, iv-F)$
$(i)$ False: It is electron-attracting in both effects.
$(ii)$ False: It is electron-attracting in both effects.
$(iii)$ True: It withdraws electrons via resonance $(-M)$ and induction $(-I)$.
$(iv)$ False: It is electron-attracting in both effects.
Final answer: $(i-F, ii-F, iii-T, iv-F)$
