Solution:

Addition reaction - a reaction in which one molecule combines with another to form a larger molecule with no other products.

$CH_2 = CH_2 + H_2 \overset{Ni}{\rightarrow} CH_3 - CH_3$

Substitution reaction – in which one functional group in a chemical compound is replaced by another functional group.

$CH_4 + Cl_2 \overset{sunlight}{\rightarrow} CH_3Cl + HCl$

Neutralisation reaction – in which an acid and base react to give salt and water

$CH_3COOH+NaOH \rightarrow CH_3COONa+H_2O$

Esterification reaction – in which an organic acid reacts with an alcohol to form an ester and water

$CH_3OH + CH_3COOH \overset{H^{+}}{\rightarrow} CH_3COOCH_3 + H_2O$
