Solution

When cracking is performed in the presence of hydrogen gas, alkanes are produced rather than alkenes.

Here's the step by step process:

  1. Cracking is a process where large hydrocarbon molecules are broken down into smaller, more useful hydrocarbon molecules.

  2. When this process is performed in the presence of hydrogen gas, it is known as 'hydrocracking'.

  3. In hydrocracking, the large hydrocarbon molecules are broken down and simultaneously, hydrogen atoms are added to the broken molecules.

  4. The addition of hydrogen atoms to the molecules prevents the formation of alkenes (which are unsaturated hydrocarbons, meaning they have double or triple bonds).

  5. Instead, alkanes are produced, which are saturated hydrocarbons with single bonds only.

  6. Therefore, the presence of hydrogen gas during the cracking process results in the production of alkanes rather than alkenes.
