Explanation

`CH_(3)-underset(CH_(3))underset(|)(CH)-CH_(2)-CH_(3)` can give four isomers of mono iodo pentane which are
`CH_(3)-underset(CH_(3))underset(|)(CH)-CH_(2)-CH_(2)-I`
`CH_(3)-underset(CH_(3))underset(|)(CH)-overset(I)overset(|)(CH)-CH_(2)`
`CH_(3)-underset(CH_(3))underset(|)overset(I)overset(|)(CH)-CH_(2)-CH_(3)` ,`CH_(3)-underset(CH_(3)-I)underset(|)(CH)-CH_(2)CH_(2)`
