Given the `IUPAC` names of the following haloalkanes and label them as primary `(1^(@))`, secondary `(2^(@))`, or tertiary `(3^(@))`
(i) tert-pentylioddie
(ii) `CH_(3)CH_(2)underset(Cl)underset(|)CHoverset(CH_(3))overset(|)(CH)CH_(3)`
(iii) Isobutyl chloride
(iv) `n`-butyl bromide
(v) `CH_(3)CH_(2)-underset(Br)underset(|)overset(CH_(3))overset(|)C-CH_(2)-overset(CH_(3))overset(|)(CH)-CH_(3)`
Isopropyl chloride
Strategy: For common names, first write the sturucture of the alkyl group, and then attach the halgon atom to the free valency.
