Question:

In the following examples, select the primary alkyl halide

(A). 1-Bromo-3-methylbutane
(B). 2-Bromo-2-methylbutane
(C). 3-Bromo propene
(D). Chlorophenyl methane

Choose the correct answer from the options given below:

Options:

(A), (C) and (D) only

(A), (B) and (D) only

(A), (B) and (C) only

(A), (B), (C) and (D)

Correct Answer:

(A), (C) and (D) only

Explanation:

The correct answer is Option (1) → (A), (C) and (D) only

A primary alkyl halide has the halogen attached to a primary carbon (a carbon bonded to only one other carbon).

Let’s analyze each compound:

  • (A) 1-Bromo-3-methylbutane → Br on primary carbon ✔️
  • (B) 2-Bromo-2-methylbutane → Br on tertiary carbon
  • (C) 3-Bromo propene → Br on primary carbon ✔️
  • (D) Chlorophenyl methane → Cl on primary carbon ✔️
