A compound is soluble in conc. H2SO4 . It does not decolourise bromine in CCL4 but in oxidised by chromic anhydride in aqueous H2SO4 with 2s , turning orange solution to blue green , afterward opaque. The original solution contains :
a primary alcohol
a secondary alcohol
a tertiary alcohol
an ether
A.
a primary alcohol
The given compounds is soluble in H2SO4 the compound should be either alcohol or ether. It does not decolourise bromine, which shows that compound does not contain double bond . Compounds is oxidised by chromic anhydride in aqueous H2SO4 i.e. compound does not contain ether group. As the oxidation is very fast, the compound (alcohol) may be a primary alcohol.
