1.	The C-Cl bond length in chlorobenzene is less than the C-Cl bond length in chloromethane because of the ________(a) resonance effect in haloarenes(b) difference in hybridisation of carbonin C-Cl bond(c) instability of phenyl cation(d) possible repulsion between nucleophile and chlorobenzeneI got this question in homework.I want to ask this question from Haloalkanes & Haloarenes topic in portion Haloalkanes and Haloarenes of Chemistry – Class 12
Answer» Right choice is (b) difference in HYBRIDISATION of carbonin C-Cl BOND To EXPLAIN I would SAY: In chlorobenzene, the C of C-Cl bond is sp^2 hybridised, whereas the C of C-Cl bond in CHLOROMETHANE is sp^3 hybridised. Thus, there is more s character in the carbon of the C-Cl bond in chlorobenzene and as a result holds the electron pair of C-Cl bond more tightly.
