Of the isomeric hexanes , the isomers that give the minimum and number

1.	Of the isomeric hexanes , the isomers that give the minimum and number of monochloro derivatives are respectively
Answer» 3-methylpentane and 2,3-dimethylbutane 2,3-dimethylbutane and n-hexane 2,2-dimethylbutane and 2-methylpentane 2,3-dimethylbutane and 2-methylpentane Solution :`overset"(1)"CH_3-underset(.^(1)CH_3)underset\|overset"(2)"CH-overset"(3)"CH_2-overset"(4)"CH_2-overset"(5)"CH_3` 2-Methylpentane has five different types of hydrogens and hence FORMS five MONOCHLORO derivatives. On the other hand , 2,3-dimethylbutane `underset"(1)"CH_3-underset(._((1))CH_3)underset\|overset"(2)"CH-underset"(1)"underset(CH_3)underset\|overset"(2)"CH-overset"(1)"CH_3`has TWO different types of hydrogens and hence forms two monochloro derivatives.
