Question

Mark the INCORRECT statement about sugar alcohol?

(a) Addition of -itol as a suffix

(b) A linear molecule that cannot cyclize

(c) Carbonyl groups reduced to a hydroxyl group

(d) Terminal -OH group oxidizes

This question was posed to me in an interview for job.

Asked question is from Carbohydrate in division Biomolecules and Catalysis of Life Sciences

Answer 1

The correct answer is (d) Terminal -OH group oxidizes

The explanation is: Sugar alcohol or alditols are formed by reduction of the carbonyl group in aldoses and ketoses to a hydroxyl group. These are designated by the addition of -itol and are linear molecules. So, terminal -OH group oxidizes is incorrect.
