Identify all the possible monochloro structural isomers expected to be formed on free radical monochlorination of `(CH_3)_(2)CHCH_(2)CH_(3)`.

Explanation

Monochloro products from 2-methyl pentane:
`CH_(3)underset(CH_(3))CHCH_(2)CH_(2)CH_(3)`
(i) `underset("1-Chloro-2-methylpentane")(ClCH_(2)underset(CH_(3))underset(|)CHCH_(2)CH_(2)CH_(3))` (ii) `underset("2-Chloro-2-methylpentane")(CH_(3)underset(CH_(3))underset(|)overset(Cl)overset(|)C CH_(2)CH_(2)CH_(3))`
(iii) `underset("3-Chloro-2-methylpentane")(CH_(3)underset(CH_(3))underset(|)CH-underset(Cl)underset(|)CH_(2)CH_(2)CH_(3))` (iv) `underset("2-Chloro-4-methylpentane")(CH_(3)underset(CH_(3))underset(|)CHCH_(2)underset(Cl)underset(|)CHCH_(3))` (v) `underset("1-Chloro-4-methylpentane")(CH_(3)underset(CH_(3))underset(|)CHCH_(2)CH_(2)CH_(2)Cl)`
