Question
Assertion: \[\ce{HI}\] cannot be prepared by the reaction of KI with concentrated \[\ce{H2SO4}\]
Reason: \[\ce{HI}\] has lowest \[\ce{H - X}\] bond strength among halogen acids.
Options
Both assertion and reason are correct statements, and reason is the correct explanation of the assertion.
Both assertion and reason are correct statements, but reason is not the correct explanation of the assertion.
Assertion is correct, but reason is wrong statement.
Assertion is wrong but reason is correct statement.
Both assertion and reason are wrong statements.
Solution
Both assertion and reason are correct statements, but reason is not the correct explanation of the assertion.
Explanation:
Because \[\ce{H2SO4}\] is a stronger oxidising agent and HIHI is a stronger reducing agent, \[\ce{H2SO4}\] oxidizes and is reduced to \[\ce{SO2}\].
