Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
If a carbohydrate has six carbon, how many hydrogens does it have?
A
3
B
6
C
9
D
12
Explanation: 

Detailed explanation-1: -Hexoses therefore have six carbons, twelve hydrogens and six oxygen atoms. Glucose is a hexose.

Detailed explanation-2: -Sugar is made up of carbon, hydrogen and oxygen atoms. It’s the way these atoms are connected that makes each type of carbohydrate different. In each molecule of table sugar there are: 12 carbon atoms, 22 hydrogen atoms, and 11 oxygen atoms.

Detailed explanation-3: -The molecular formula is C6H12O6 because one molecule actually contains 6 C, 12 H, and 6 O atoms. The simplest whole-number ratio of C to H to O atoms in glucose is 1:2:1, so the empirical formula is CH2O.

Detailed explanation-4: -Glucose has an aldehyde group (-CHO) on carbon atom number one and is therefore called an “aldose, ‘’ also it has six carbon atoms (a hexose) so it can be called an “aldohexose.” The reactive group on fructose, however, is a ketone group (-C=0) on carbon number two.
