Give the IUPAC names of the compounds. Classify them as alkyl, allylic, benzylic, vinylic and aryl halides and also as primary, secondary and tertiary halides.
` (i ) (CH_3)_3 C CH_2 CH (Cl) CH_3`
`(ii ) CH_3 CH_2 CH=CHCH_2 Cl,`
`(iii ) (CH_3)_2 CHCH_2 CH=C (Cl) CH_2 CH_3 and `
`(iv ) C_6 H_5 C (Cl ) CH_3)_2`

Explanation

`(i) underset("2- chloro-4,4- dimethylpentane alkyl halide ( secondary)") ( H_3 overset(5)(C ) - underset(CH_3) underset(| ) overset( CH_3) overset(4|) (C ) - overset(3 )(CH_2) - underset(Cl ) underset(| ) overset(2)(CH) - overset(1) (CH_3))`
`(ii ) underset("1-Chloropent-2-ene Allylic halide ( primary )") ( overset(5) (CH_3) overset(4)(CH_2) overset(3) (CH)= overset(2) (CH)overset(1)(CH_2) Cl)`
`(iii ) underset("2-chloro-2-phenylpropane henzylic halide ( tertiary)") ( C_6 H_5 - underset(CH_3) underset(| ) overset(Cl)overset(|)(C ) - CH_3)`
