| Assertion: Electron withdrawing groups in aryl halides decrease the reactivity towards nucleophilic substitution. |
| Reason: 2, 4-Dinitrochlorobenzene is more reactive than chlorobenzene. |
A) Assertion and reason both are correct statements and reason is correct explanation for assertion.
B) Assertion and reason both are correct statements but reason is not correct explanation for assertion.
C) Assertion is correct statement but reason is wrong statement.
D) Assertion is wrong statement but reason is correct statement.
Correct Answer: D
Solution :
Halobenzenes become reactive to nucleophilic substitution reactions when electron withdrawing group (nitro, cyano) are present at ortholpara position. This is evident from the milder conditions required for hydrolysis in 2,4-dinitrochlorobenzene than chlorobenzene.
