Formal charge,Resonance and Resonating structures

Which among the following statements are true with respect to electronic displacement in a covalent bond? (1) Inductive effect operates through a pi - bond (2) Resonance effect operates through a sigma -bond (3) Inductive effect operates through a sigma -bond (4) Resonance effect operates through a pi- bond (5) Resonance and inductive effects operate through sigma -bond

A: Aniline is not prepared by Gabriel phthalimide synthesis. R: Due to partial double bond character in haloarene because of resonance.

Resonance, Condition for Resonance

Assertion: It is difficult to replace chlorine by -OH in chlorobenzene in comparison to that in chloroethane Reason: Chlorine-carbon (C-Cl) bond in chlorobenzene has a partial double bond character due to resonance.
