Question

Propane when treated with cold cone. H₂SO₄ forms a compound which on heating with water gives ______.

Options

• propan-2-ol

• butan-1-ol

• ethanol

• propan-1-ol

Answer 1

Propane when treated with cold cone. H₂SO₄ forms a compound which on heating with water gives propan-2-ol.

Explanation:

When propane is treated with a cold cone, it becomes propane. When H2S04 is heated with water, it creates the chemical isopropyl- hydrogen sulphate, which produces propan-2-ol.
