Derive the structure of (i) 2-Chlorohexane, (ii) Pent-4-en-2-ol, (iii) 3- Nitrocyclohexene, (iv) Cyclohex-2-en-1-ol, (v) 6-Hydroxy- heptanal.

Explanation

(i) Pent-4-en-2-ol ‘Pent’ indicates that parent hydrocarbon contains 5 carbon atoms in the chain ‘en’ and ‘ol’ correspond to the functional groups C = C and -OH at carbon atoms 4 and 2 respectively. Thus, the structure is
`CH_(2)=CHCH_(2)CH(OH)CH_(3)`
(ii)Cyclohex-2-en-1 -ol ‘1-ol’ means that a -OH group is present at C - 1, OH is suffixed functional group and gets preference over C = C bond. Thus, the structure is
