Solution:

In Victor Meyer's test, blue colour salt is given by secondary alcohols. It means compound must be a secondary alcohol. Only aldehydes with Grignard reagent yield secondary alcohols. Aldehyde should have one carbon less than the secondary alcohol since Grignard reagent contains methyl group. These conditions are satisfied by acetaldehyde and isopropyl alcohol.
