Given the balanced equation representing a reaction:
CH3CH2CH3 + Br2==> CH3CH2CH2Br + HBr
This organic reaction is best classified as
(1) an addition reaction
(2) an esterification reaction
(3) a polymerization reaction
(4) a substitution reaction



Answer :

The answer is (4) a substitution reaction. Notice that propane lost an H and gained a Br. This constitutes substitution.
