Which statement accurately describes the process of pyrolysis of alkanes?

Options

  1. APyrolysis is an endothermic reaction.
  2. BPyrolysis of alkanes yields higher alkanes.
  3. CPyrolysis is a free radical reaction that decomposes alkanes into smaller fragments upon heating.
  4. DPyrolysis of alkanes is an isomerization reaction.

Correct answer

C. Pyrolysis is a free radical reaction that decomposes alkanes into smaller fragments upon heating.

Step-by-step solution

Pyrolysis is a process that involves the decomposition of alkanes into smaller fragments, such as lower alkanes and alkenes, by the application of heat. This reaction is believed to proceed through free radical mechanisms.
