These are examples of five different reaction types.

(i) #"CH"_3"CH"_3 + "Cl"_2 → "CH"_3"CH"_2"Cl" + "HCl"#

This is a free radical substitution reaction.

(ii) #"CH"_3"CH(OH)CH"_3 → "CH"_3"CH=CH"_2 + "H"_2"O"#

This is a dehydration or elimination reaction.

(iii) #"CH"_3"CHO" + "HCN" → "CH"_3"CH(OH)CN"#

This is a nucleophilic addition reaction.

(iv) #"CH"_3"CH=CH"_2 + "HBr" → "CH"_3"CHBrCH"_3#

This is an electrophilic addition reaction.

(v) #"CH"_3"CH"_2"C(OH)=CH"_2 ⇌ "CH"_3"CH"_2"COCH"_3#

This is an example of keto-enol tautomerism.
