An alkanol can be prepared by the reaction of an alkene with
concentrated tetraoxosulphate (VI) acid
bromine tetrachloroethane
aqueous potassium tetraoxomanganate (VII)
sodium hydroxide solution
Explication
An alkene reacts with conc. H\(_2\)SO\(_4\) to yield an alkyl hydrogen tetraoxosulphate (VI). The compound formed undergoes hydrolysis when boiled with water to yield an alcohol.
