Give reasons: (i) C–Cl bond length in chlorobenzene is shorter than C–Cl bond in CH_(3)Cl. (ii) The dipole moment of chlorobenzene is lower than that of cyclohexyl chloride (iii) SN_(1) reactions are accompained by racemization in optically active alkyl halides |

Answer» SOLUTION :(i) In chlorobenzene, each carbon atom is `sp^(2)` hybridised/ resonating structures / partial donable bond character. (II) Due to + R effect in chlorobenzene / difference in hybridization i.e., `sp^(2)` and `sp^(3)` RESPECTIVELY (iii) Due to formation of planer CARBOCATION |
