Assertion (A) HI cannot be prepared by the reaction of KI with concentrated `H_(2)SO_(4)`.
Reason (R ) HI has lowest H___X bond strenth among halogen acids.

A

Both Assertion and Reason are correct statements , and Reason is the correct explation of the Assertion.

B

Both Assertion and Reason are correct statements , and Reason is not the correct explanation of the Assertion.

C

Assertion is correct, but Reason is wrong statement.

D

Assertion is wrong but Reason is correct statement.

Text Solution

Verified by Experts

Both assertion and reason are correct statements, but reason is not the correct explanation of the assertion.
HI cannot be prepared by the reaction of KI with concentrated `H_(2)SO_(4)` because HI is converted into `I_(2)` on reaction with `H_(2)SO_(4)`.
