Hydrocarbons & Chemical Industries: Class 10 Chemistry Worksheet

Crude oil is a mixture of hydrocarbons formed over millions of years from the remains of ancient marine organisms. Fractional distillation separates it into fractions, from low-boiling refinery gas to bitumen for surfacing roads. The questions are multiple choice (four options each) on petroleum, its fractions and their uses, and the worksheet carries 15 marks.
