Question

Which one of the following gives only one monochloro derivative? (A) neo-Pentane (B) n-Hexane (C) 2-Methylpentane (D) 3-Methylpentane

Tardigrade Admin · Accepted Answer

neo-Pentane or 2, 2-dimethylpropane has only primary hydrogen hence it can give only monochloro derivative. All other compounds have 1°, 2° and 3° hydrogens hence they give mono, di or trisubstituted products.

Q. Which one of the following gives only one monochloro derivative?

$n eo$ -Pentane

$n$ -Hexane

$2$ -Methylpentane

$3$ -Methylpentane

$n eo$ -Pentane or $2$ , $2$ -dimethylpropane has only primary hydrogen hence it can give only monochloro derivative. All other compounds have $1^{\circ}$ , $2^{\circ}$ and $3^{\circ}$ hydrogens hence they give mono, di or trisubstituted products.
