In terms of its electronic properties, the phenyl group is related to a vinyl group. It is generally considered an inductively withdrawing group (-I), because of the higher electronegativity of sp carbon atoms, and a resonance donating group (+M), due to the ability of its π system to donate electron density when conjugation is possible. The phenyl group is hydrop… indian restaurants in banff
