Question

In carbohydrates, the ratio of hydrogen: oxygen is ________.

Answer 1

Carbohydrates:-

• Carbohydrates have the stoichiometric formula ${\left({\mathrm{CH}}_2\mathrm{O}\right)}_{\mathrm{n}}$, where n represents the number of carbons in the molecule.
• Therefore, in carbohydrate molecules the ratio of Hydrogen to Oxygen is $2:1$.
• Carbohydrates are the main source of energy for the body.
• Example: Fructose is known to be a carbohydrate having a formula i.e ${\mathrm{C}}_6{\mathrm{H}}_{12}{\mathrm{O}}_6$
• Here the given carbohydrate has $5$ Carbon atoms, $10$ Hydrogen, and $5$ Oxygen.
• Hence, the ratio of hydrogen: oxygen can be given as: $\mathrm{H}:\mathrm{O}=10:5=2:1$

Hence, in carbohydrates, the ratio of hydrogen: oxygen is $2:1$.
