Assertion : 2-Butanol on heating with \(\mathrm{H}_{2} \mathrm{SO}_{4}\) gives 1-butene and 2-butene. Reason : Dehydration of 2-butanol follows Saytzeff rule.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but Reason is correct.
Explanation:
In the dehydration of secondary and tertiary alcohols, when there is a possibility of formation of two isomers, the hydrogen atom is preferentially eliminated from the adjacent carbon atom with the fewer number of hydrogen atoms. This is known as Saytzeff's rule \(\mathop {{\text{C}}{{\text{H}}_{\text{3}}}{\text{C}}{{\text{H}}_{\text{2}}}{\text{CH = C}}{{\text{H}}_{\text{2}}}}\limits_{{\text{1 - Butene(20 % )}}} {\text{ + }}\mathop {{\text{C}}{{\text{H}}_{\text{3}}}{\text{CH = CHC}}{{\text{H}}_{\text{3}}}}\limits_{{\text{2 - Butene(80 % )}}} \) So, option (1) is correct
