Although (IV) is an hydroxy ketone and hence reducing but it can t mutarotate as it not a carbohydrate, can t form ring. In (II) the glycosidic linkage is in between two anomeric carbons and hence ring opening can t occur, thus non reducing as well as non mutarotating. 9. B, D In B and D compound after mixing undergoes bonding and hence boiling point will be raised and hence vapour pressure lowered. 1.
