Answer 2

Methyl Bromide is more reactive than the 2-chlorobutane towards KI / Acetone .

• The KI / acetone reaction follows the SN2 mechanism .

• Reactivity due to degree of carbon : methyl > 1° > 2° > 3°
• Reactivity due to halides : I > Br > Cl > F
• Thus , the Methyl Bromide is more reactive than 2-chlorobutane by the above given thoery . Hence , the option ( C ) is the correct option .
