Correct Answer - B
Alkyl halide undergoes rearrangement `underset("n-Propyl chloride")(CH_(3)CH_(2)CH_(2)Cl)underset(-Cl^(-))rarr underset((1^(@)))(CH_(3)CH_(2)CH_(2)+)rarr underset((2^(@)))(CH_(3)overset(+)(C )H-CH_(3))overset(Cl^(-))rarr underset("2-Chloropropane")(CH_(3)-underset(Cl)underset(|)(C )H-CH_(3))`
