Question 5

THREE MAJOR TYPES OF REACTIONS

Answer 5

COMBUSTION REACTIONS - burn them - destroying thr entire molecule;

HALOGENATION REACTIONS - react with some of the halogens, breaking the carbon-hydrogen bonds.

CRACKING REACTIONS - use heat and/or a catalyst to crack alkanes, breaking carbon-carbon bonds.
