Q. Of the five isomeric hexanes, the isomer which can give two monochlorinated compounds is
A) 2-methylpentane
B) 2,2-dimethylbutane
C) 2, 3-dimethylbutane
D) n-hexane
Explanation
(c)
2-methylpentane$\overset{\ \ \ \ \ \ \ \ Cl_{2}\ \ \ \ \ }{\rightarrow}$ five types of monochlorinated compounds
3-methylpentane$\overset{\ \ \ \ \ \ \ \ Cl_{2}\ \ \ \ \ }{\rightarrow}$ four types of monochlorinated compounds
2, 2-dimethylbutane$\overset{\ \ \ \ \ \ \ \ Cl_{2}\ \ \ \ \ }{\rightarrow}$ three types ……
2, 3-dimethylbutane$\overset{\ \ \ \ \ \ \ \ Cl_{2}\ \ \ \ \ }{\rightarrow}$ two types ….
$n$-hexane$\overset{\ \ \ \ \ \ \ \ Cl_{2}\ \ \ \ \ }{\rightarrow}$ three types ….
