Cracking Hydrocarbons: Converting Heavy Fractions to Lighter Fractions

The video tutorial explains the demand for lighter fractions of crude oil, which are used as fuels, compared to heavier fractions. It introduces the cracking process, which converts heavier hydrocarbons into lighter, more useful ones. The tutorial provides an example of cracking decane into heptane and propane, highlighting the properties of alkanes and alkenes. It discusses the uses of these hydrocarbons, such as fuels and polymers, and explains the bromine water test to differentiate between alkanes and alkenes.

How can bromine water be used to distinguish between alkanes and alkenes?

What happens to bromine water when it reacts with an alkene compared to an alkane?
