When large hydrocarbon molecules are heated at high temperature in the presence of a catalyst to give smaller molecules, the process is known as?

A. disintegration
B. polymerization
C. cracking
D. degradation

Correct Answer:

Option C – cracking

Explanation

Cracking is the breakdown of a large alkane into smaller, more useful alkenes. Simply put, hydrocarbon cracking is the process of breaking a long-chain of hydrocarbons into short ones. This process might require high temperatures and high pressure.
