Question

Name a ketose sugar containing 7 carbon atoms.

a. Fructose (hexose)
b. Ribose (pentose)
c. Glucose (hexose)
d. None

Answer 1

None of the option is right for the question "Name a ketose sugar containing 7 carbon atoms."

The correct option is d.

Step-by-step explanation:

Ketose sugars are commonly found in three-carbon (triose), five-carbon (pentose), and six-carbon (hexose) structures. There isn't a well-known ketose sugar containing seven carbon atoms. Among the options provided, fructose, ribose, and glucose are either hexose or pentose sugars, none of which match the description of a ketose sugar with seven carbon atoms.

So, the correct option is d.
