ChemistrySingle correct+4 / -1Question 80 of 90

Given below are two statements : one is labelled as Assertion (A) and the other is labelled as Reason (R).

Assertion (A) : Experimental reaction of $\mathrm{CH_3Cl}$ with aniline and anhydrous $\mathrm{AlCl_3}$ does not give o and p-methylaniline.

Reason (R) : The $-\mathrm{NH_2}$ group of aniline becomes deactivating because of salt formation with anhydrous $\mathrm{AlCl_3}$ and hence yields m-methyl aniline as the product.

In the light of the above statements, choose the most appropriate answer from the options given below :

Both (A) and (R) are true and (R) is the correct explanation of (A).

Both (A) and (R) are true but (R) is not the correct explanation of (A).

(A) is true, but (R) is false.

(A) is false, but (R) is true.

Answer and worked solution

Official answer: C

Assertion true: no o/p products form. Reason false: the anilinium-AlCl₃ complex is deactivated and Friedel-Crafts fails altogether rather than giving m-methylaniline.

(C)

Topics:Amines Aromatic hydrocarbons and electrophilic substitution
