A primary alkyl halide would prefer to undergo

• A. $S_N1$ reaction
• B. $S_N2$ reaction
• C. $\alpha -$ elimination
• D. Racemization

$S_N2$ reaction

Answer 2

Due to little steric hindrance and least stability of $1^{\circ}$ carbocations, $1^{\circ}$ alkyl halides prefer to undergo $S_N2$ reactions.
