Where do alkanes come from

Question 1

Where do alkanes come from?
Although they are relatively available, alkanes are produced by two main processes:

Answer 1

Fractional distillation of crude oil

Hydrogenation of alkenes

Question 2

Fractional distillation of crude oil involves

Answer 2

This process involves separating a mixture of hydrocarbons into different fractions according to their boiling points.

Question 3

Hydrogenation of alkenes involve

Answer 3

This process is generally used to produce specific alkanes and convert them into more reactive halogenoalkanes
