11.3 (i) 3-chloroethyl-2-isopropylpentan-1-ol

        (ii) 2,5-Dimethylhexane-1,3-diol

        (iv) 3-Bromocyclohexanol

        (v) Hex-1-en-3-ol

        (vi) 2-Bromo-3-methylbut-2-en-1-ol

11.2 Allylic alcohol is an organic compound which has the structural formula CH₂ = CHCH₂OH. In other words, in these alcohols, the-OH group is attached to sp² hybridized carbon next to the carbon-carbon double bond, that is to an allylic carbon. Therefore, in the above examples, the following are the allylic alcohols.

(ii) H₂C = CH – CH₂OH and

It is primary alcohol because carbon which carries the –OH group is only attached to one alkene group.

It is primary alcohol because the carbon which carries the –OH group is only attached to one propyl group.

It is secondary alcohol because the carbon which carries the –OH group is joined directly to methyl and benzene.

It is secondary alcohol because the carbon which carries the –OH group is joined directly to two different alkyl groups.
