Question

Glucose can exist in both a straight chain and ring form.

(a) True

(b) False

This question was posed to me during a job interview.

The above asked question is from Biomolecules Carbohydrates topic in division Biomolecules of Chemistry – Class 12

Answer 1

Right choice is (a) True

To explain I would say: This is due to the observations where glucose in most cases behaves as an aldehyde and in some cases does not. This led to speculation of the existence of glucose in other forms where the CHO group was not present. The ring form of glucose was subsequently discovered.
