Question:
Carbohydrate molecules are characterized by any one of the following groups EXCEPT ___________.
Carbohydrate molecules are characterized by any one of the following groups EXCEPT ___________.
Show Hint
{Carbohydrates = aldehyde/ketone + hydroxyl groups}.
Updated On: Feb 4, 2026
- aldehyde (CNO)
- hydroxyl (OH)
- carboxyl (COOH)
- ketone (C=O)
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Basic structure of carbohydrates.
Carbohydrates are polyhydroxy aldehydes or ketones.
Step 2: Functional groups present.
They contain hydroxyl groups along with either an aldehyde or ketone group.
Step 3: Identifying the exception.
Carboxyl group (COOH) is not a characteristic functional group of carbohydrates.
Carbohydrates are polyhydroxy aldehydes or ketones.
Step 2: Functional groups present.
They contain hydroxyl groups along with either an aldehyde or ketone group.
Step 3: Identifying the exception.
Carboxyl group (COOH) is not a characteristic functional group of carbohydrates.
