NEETChemistryHaloalkanes and Haloarenes
Which of the following statements are correct? A. The C - Cl bond in chlorobenzene is shorter than in chloromethane. B. It is difficult to replace chlorine from chlorobenzene than from benzyl chloride. C. The C - Cl bond in chlorobenzene has some double bond character. D. Chlorobenzene on chlorination gives m-dichlorobenzene
Options
- AA, B, C
- BA, D only
- CB, C, D
- DC, D only
Correct answer
A. A, B, C
Step-by-step solution
Chlorobenzene has double bond character between C and Cl . So, it is difficult to replace form than form benzyl chloride. (c) C - Cl has double bond character in chlorobenzene. (d) Chlorobenzene on chlorination gives m -dichlorobenzene due to o / p -directing effect of Cl . Thus, option (a) is correct.
