Question

The reaction of $C_2{H}_{5}OH$ with $H_{2}S{O}_4$ does not give

• A. Ethylene
• B. Diethyl ether
• C. Acetylene
• D. Ethyl hydrogen sulphate

Answer 1

The correct option is C Acetylene

Ethanol in presence of conc. Sulphuric acid gives ethylene at ${170}^{\circ }C.$

At lower temperature of ${140}^{\circ }C$ it gives diethyl ether.

At ${70}^{\circ }C-{110}^{\circ }C$ ethanol dehydrates to give ethyl hydrogen sulphate.
