Which two functional groups are characteristic of sugars?(a) Carbonyl

1.	Which two functional groups are characteristic of sugars?(a) Carbonyl and phosphate(b) Carbonyl and methyl(c) Hydroxyl and methyl(d) Carbonyl and hydroxyl
Answer» The correct option is(d) Carbonyl and hydroxyl Explanation: Sugars are chemically carbohydrates. They are polyhydroxy aldoses, ketoses, and their condensation products. Aldoses bear a terminal aldehyde or -CHO group while ketoses have an internal ketone or -CO group. Thus, they possess two functional groups, i.e. carbonyl and hydroxyl.
