1.	Which of following species does not exert a resonance effect
Answer» `C_(6)H_(5)OH` `C_(6)H_(5)CL` `C_(6)H_(5)NH_(2)` `C_(6)H_(5)NH_(3)` Solution :`C_(6)H_(5)NH_(2)+H^(+)rarrunderset("ANILINIUM ion")(C_(6)H_(5)overset(+)(NH_(2))` Anilinium ion formed by ANILINE on accepting a proton is less resonance stabilised than aniline. Due to absence of lone pair in conjugation of double bond of BENZENE it does not exert a resonance effect.
