स्नेहक तेल lubricating oil

पेट्रोल Petrol

कोक Coke

​

Answer 1

Coke is not a constituent of petroleum.

• The components obtained from crude oil can be separated through fractional distillation. Crude oil also has paraffin wax.
• The fractional distillation of crude oil yields lubricating oil, petroleum, petrol, diesel, kerosene etc.
• However, coke is not a part of the fractional distillation of crude oil.
• Coke is produced when we heat coal in the absence of air and hence it is a component of carbon.
