Question

Which of the following analogies is correct?
$\text{Isopropyl chloride}:2^o\text{alkyl halide}::\text{Isobutyl chloride}:$

• A. $1^o\text{alkyl halide}$
• B. $2^o\text{alkyl halide}$
• C. $3^o\text{alkyl halide}$
• D. None of these

Answer 1

The correct option is A $1^o\text{alkyl halide}$


In isopropyl chloride, the chlorine is attached to a carbon that is only attached to two other carbon hence it is secondary halide. Whereas in isobutyl chloride, the chlorine is attached to a carbon that is only attached to one other carbon hence it is primary alkyl halide.
