Saytzeff's rule: The alkene formed in greatest amount is the one that corresponds to removal of the hydrogen from the β -carbon having the fewest hydrogen substituent. In case of 2° and 3° alc. Saytzefi's rule is followed <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/chemistry/ae40afcade4c1f86a9602d9ac869e13f-.png" />

Q. Assertion : 2 - Butanol on heating with $H_{2} S O_{4}$ gives 1 - butene and 2 - butene.
