Answer to Question #192595 in Organic Chemistry for Ola

Question

Write equations and explain reactions of alkanes – combustion, chlorination, cracking.

Answer 1

In thermal cracking, high temperatures (typically in the range of 450 °C to 750 °C) and pressures (up to about 70 atmospheres) are used to break the large hydrocarbons into smaller ones. Thermal cracking gives mixtures of products containing high proportions of hydrocarbons with double bonds - alkenes.
