Question

Dehydration of ……. Alcohols is carried out with concentrated sulphuric acid.
A. Primary
B. secondary
C. tertiary
D. all of these

Answer 1

Correct Answer - A
The acid acts as dehydrating agent. The dehydration of `2^(@) and 3^(@)` alcohols is best carried out using dilute `H_(2)SO_(4)` because the alkenes formed from this alcohol tend to polymerize under the influence of concentrated acid.
