Answer 1

a) bromine and hex-2-ene; b) chlorine and benzene

Explanation:

a) 2,3-Dibromohexane

This is an example of an addition reaction.

`underbrace("CH"_3"CH"_2"CH"_2"CH=CHCH"_3)_color(red)("hex-2-ene") + "Br"_2 → underbrace("CH"_3"CH"_2"CH"_2"CHBrCHBrCH"_3)_color(red)("2,3-dibromohexane")`

b Chlorobenzene

This is an example of a Friedel-Crafts reaction.

`underbrace("C"_6"H"_6)_color(red)("benzene") + "Cl"_2 stackrelcolor(blue)("FeCl"_3color(white)(mm))(→) underbrace("C"_6"H"_5"Cl")_color(red)("chlorobenzene") + "HCl"`
