1.	Assertion. Rates of nitration of benzene and hexadeuterobenzene are different. Reason. C-H bond is stronger than C-D bond.
Answer» If both assertion and reason are true, and reason is the true explanation of the assertion. If both assertion and reason are true, but reason is not the true explanation of the assertion. If assertion is true, but reason is false. If both assertion and reason are false Solution :CORRECT assertion. Rates of NITRATION of BENZENE and hexadeuterobenzene are same. Correct assertion. The C-D or C-H BOND is not involved in rate-determining step of the REACTION.
