Question

so if you only know the chemical formula of a sugar, you cannot tell what molecule it is. what is the difference between glucose and fructose? a) number of oxygen atoms linked to carbon atoms b) arrangement of functional groups c) number of double bonds d) chemical formula

Explanation:

Glucose and fructose have the same chemical formula ($C_6H_{12}O_6$), same number of oxygen - carbon linkages and double bonds. The key difference lies in the arrangement of their functional groups. Glucose is an aldose with an aldehyde group, while fructose is a ketose with a ketone group.

Answer:

B. Arrangement of functional groups
