Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
General Chemical Formula of Carbohydrate is?
A
(CH2O)n
B
(CH2O)2n
C
(CHO)n
D
CnH2nO
Explanation: 

Detailed explanation-1: -The general chemical formula of carbohydrate is (CH2O)n. For example-in the case of glucose, substitute n=6, then the chemical formula of glucose is C6H12O6.

Detailed explanation-2: -Carbohydrates have the general molecular formula (CH2O)n. These are simple sugars that serve as fuel molecules as well as fundamental constituents of living organisms, are the simplest carbohydrates, and are required as energy sources. The most commonly known ones are perhaps glucose and fructose.

Detailed explanation-3: -Formaldehyde is a naturally occurring organic compound with the formula CH2O (H-CHO).

Detailed explanation-4: -CH2O is a general formula for any carbohydrate. One can recognize a carbohydrate because the ratio of hydrogen atoms to oxygen atoms is 2:1 as in the formula CH2O.
