Question

Which of the following is a primary alkyl halide?

• A. Neohexyl chloride
• B. Isopropyl iodide
• C. Tertiary butyl bromide
• D. None of the above

Answer 1

The correct option is A Neohexyl chloride

In primary alkyl halide, number of hydrogens present on ​the C-atom of $s{p}^3$ C-X bond is 2.
Neohexyl chloride is primary halide since number of hydrogens present on ​the C-atom of $s{p}^3$ C-Cl bond is 2.
Isopropyl iodide is secondary halide since number of hydrogens present on ​the C-atom of $s{p}^3$ C-I bond is 1.
Tertiary butyl bromide is tertiary halide since number of hydrogens present on ​the C-atom of $s{p}^3$ C-Br bond is 0.
