Question

Which of the following halide is $2^o$?

• A. Isopropyl chloride
• B. n-propyl chloride
• C. n-butyl chloride
• D. Iso-butyl chloride

Answer 1

The correct option is A Isopropyl chloride

Isopropyl chloride is secondary/$2^o$ halide since number of hydrogens present on ​the C-atom of $s{p}^3$ C-Cl bond is 1.

n-propyl chloride and n-butyl chloride is primary/$1^o$ halide since number of hydrogens present on ​the C-atom of $s{p}^3$ C-Cl bond is 2.
