Hydrolysis of the addition products of hydrogen chloride to isoprene

By hydrolysis of the addition products of hydrogen chloride and isoprene, 1-chloro-3-methylbutene-2 [CH3. C(CH3):CH. CH2Cl) and 3-chloro-3-methylbutene-1 (CH3. CCl(CH3). CH:CH2], the main product is isoprene alcohol, CH3. C(CH3OH. CH:CH2 (3-methyl-3-hydroxybutene-1) along with a compound, which is very probably prenol1 ) CH3. C(CH3):CH. CH2OH, also.
