Answer :
Solution :
In IUPAC system of nomenclature, preference is given to multiple bond than halogen substituent, so the correct name of $$Br - \mathop {\mathop {C{H_2}}\limits^3 - \mathop {CH}\limits^2 = \mathop {C{H_2}}\limits^1 }\limits_{3{\text{ }} - bromoprop - 1 - ene} $$ is Priority is given to double bond than halogen.
