Question

What is the major product when 1-bromopropane undergoes nucleophilic substitution with \(OH^-\)?

• A. Propan-1-ol
• B. Propan-2-ol
• C. 1,2-Propanediol
• D. Propene

Hint:

In \(S_N2\) reactions, a \(1^\circ\) halide undergoes nucleophilic substitution to form the alcohol with inversion of configuration.

Answer 1

The Correct Option is A

1-Bromopropane undergoes nucleophilic substitution with hydroxide ion (\(OH^-\)) to form an alcohol. The reaction follows an \(S_N2\) mechanism because \(1^\circ\) halides undergo \(S_N2\) substitution. The reaction is: \[ \text{CH}_3\text{CH}_2\text{CH}_2\text{Br} + OH^- \rightarrow \text{CH}_3\text{CH}_2\text{CH}_2\text{OH}. \] Thus, the major product is propan-1-ol. The correct answer is: \[ \boxed{\text{Propan-1-ol}}. \]
