Question

Are glucose and fructose structural isomers?

Answer 1

1. Structural Isomers - In chemistry compounds which have the same molecular formula but different structures are known as structural isomers.
2. Glucose $\left({\mathrm{C}}_6{\mathrm{H}}_{12}{\mathrm{O}}_6\right)$ and Fructose $\left({\mathrm{C}}_6{\mathrm{H}}_{12}{\mathrm{O}}_6\right)$ have the same molecular formula but their atoms are bonded differently with one another giving them both different structures.
3. The structure of Glucose and Fructose is given below -

Hence glucose and fructose are structural isomers.
