Define a substitution reaction.
A substitution reaction is a chemical reaction in which an atom or group of atoms in a molecule is replaced by another atom or group of atoms
Give an example of a substitution reaction undergone by alkanes.
Alkanes reaction with halogens in the presence of ultraviolet light
During the reaction of chlorine with methane, what occurs?
One of the hydrogen atoms in methane has been replaced (substituted) by a chlorine atom to form the new compound chloromethane
What occurs during the reaction between chlorine and methane if excess chlorine is used?
Further substitution takes place to form dichloromethane (CH2Cl2), trichloromethane (CHCl3) and eventually tetrachloromethane (CCl4)
What is the process of replacing just one atom of hydrogen with one atom of chlorine called?
Monochlorination
What is monochlorination?
The replacing of one atom of hydrogen with one atom of chlorine
