Question

The general chemical formula of carbohydrate is:

• A. (CH${}_2$O)${}_n$
• B. (CH${}_2$O)${}_2$${}_n$
• C. (CHO)${}_n$
• D. C${}_n$H${}_2$${}_n$O

Answer 1

The correct option is A (CH${}_2$O)${}_n$

The general chemical formula of carbohydrate is (CH${}_2$O)${}_n$. For example - in the case of glucose, substitute n=6, then the chemical formula of glucose is $C_6{H}_{12}{O}_6$.
