3.5 I can recall the reaction of methane and bromine

Alkanes react with bromine in the presence of UV Light
     Explain why this condition is necessary  UV light is the source on energy in order to break the weak inter molecular forces in between molecules.
  What is this type of reaction called A substitution reaction 
 State and explain the observations - Alkanes are colourless and bromine is brown, when the reactants are given energy to break intermolecular bonds the bromine is less saturated and the product is therefore colourless 
Write out a balanced (with state symbols) the reaction between ethane and chlorine
C2H+ Clà C2H5 + HCl
 State and explain the observations in this chemical reaction
The chorine begins as a green/yellow gas, when it reacts the chlorine is less saturated and the product is more saturated making the product colourless
