1.	(a) If both assertion and reason are true and the reason is the correct explanation of the assertion of the assertion. (b) If both assertion and reason are true but reason is not the correct explanation of the assertion. (c) If assertion is true but reason is false. (d) If assertion is false but reason is true. Q. Assertion: Aniline does not undergo Friedel-Crafts reaction. Reaction: Friedel-Crafts is an electrophilic substitution reaction.
Answer» Correct Answer - B correct explanation `AlCl_3` forms a salt with aniline `(C_6H_5NH_2^(+)AlCl_3^(-))` which deactivates the benzene ring there by preveting F.C. reaction.
