Vedclass · Answer

(D) The open-chain structure of glucose is $CHO-(CHOH)_4-CH_2OH$.In this structure,the four $-CHOH-$ groups are attached to two other carbon atoms,making the hydroxyl groups attached to these carbons secondary $(2^{\circ})$ hydroxyl groups.The $-CH_2OH$ group at the end is a primary $(1^{\circ})$ hydroxyl group.Therefore,there are $4$ secondary hydroxyl groups in glucose.
