Assertion: Dehydration of alcohols can be carried out with conc. H2SO4 but not with conc. HCl.
Reason: H2SO4 is dibasic while HCl is monobasic.

A
Both Assertion and Reason are true and Reason is the correct explanation to Assertion
B
Both Assertion and Reason are true and Reason is not the correct explanation to Assertion
C
Assertion is true but Reason is false
D
Assertion is false but Reason is true
Solution
Verified by Toppr

Dehydration of alcohols can be carried out with conc. H2SO4 as it is a dehydrating agent and removes a molecule of water from alcohols resulting in the formation of alkenes at higher temperatures. Conc. HCl is not a dehydrating agent.
H2SO4 is indeed a dibasic acid and HCl is not. But it is not the reason that HCl is not a dehydrating agent.

So, both assertion and reason are true but the reason is not the correct explanation to assertion.
The correct option is 'B'.
