Question

Draw two structures (one straight chain and one ring) of a carbohydrate with the chemical formula (CH2O6).

How would i do this??

Answer 1

The chemical formula CH2O6 is not a carbohydrate unless it was written this way:
(CH2O)6 which is now the chemical formula of glucose.
Glucose has a linear and a cyclic structure. I will attach the structures since it's difficult to describe the drawing. The first one is straight chain and the next one is the ring.

Answer 2

I think you mean (CH2O)6, it is the formula for glucose (or it could be written C6H12O6).

The linear structure is characterized by the presence in the same molecule of a reducing function aldehyde or ketone and at least one alcohol function.

On the other hand, this linear form can be transformed into a cyclic form (in the solutions), and this implies the formation of hemiacetal by bonding between the aldehyde of carbon 1 and the alcohol of the penultimate carbon.
