What is crack?

Answer 1

Cracking takes place after the process of fractional distillation.

It is the process of braking down the larger, less useful hydrocarbons into smaller, more useful molecules.

How is it done?

This process involves heating the hydrocarbons to vapourise them and passing the vapours over a hot catalyst.

The products of this process are a smaller alkane and an alkene.

This is called a thermal decomposition reaction.

Answer 2

AnswerCocaine cut (mixed) with usually something like ammonia so that once the two combine, the end result is a "cracked back" form of the once powder cocaine.
