Explain why glucose is written as C6H12O6 not as CH20?

Answer 1

its c12h22o11 because H2O is removed during the making of maltose due to condensation reaction. so if u take away 2h and 1o from c12h24o12 it will be c12h22o11 That's true, but WHY? Why is it necessary to form a molecule of water every time you make a molecule of maltose? It's due to the need for a bonding site on each of the two glucose molecules. A glucose molecule is smooth like a chrome bumper--nothing can stick to it, because it doesn't have any open bonding sites. If you want to stick something more substantive than a sticker to a chrome bumper, you need to sand the bumper to create an area that's rough enough to hold glue. If you want to stick two carbohydrates together, you need to rough them up by removing one hydrogen atom from one carbohydrate and a hydroxyl group from another. Once this is done, the hydrogen and hydroxyl will find each other and create a molecule of water, and the two stripped monosaccharides will find each other's open bonding site and create a molecule of maltose.

Answer 2

Because Glucose is a molecular compound. Ionic compounds, who don't form definite molecules, are written in formulas with ratios. Because Glucose exists as a rigid molecule with 6 actual carbon atoms, 12 actual hydrogen atoms, and 6 actual oxygen atoms, therefore, it is written in a molecular formula that way. Ionic compounds, such as NaCl, don't form molecules, they only cohabitate in ratios of 1:1.

Answer 3

Glucose has a molecular formula of C6H12O6 because it contains 6 carbon atoms, 12 hydrogen atoms, and 6 oxygen atoms. The formula CH2O represents the general molecular formula for a carbohydrate unit, but in the case of glucose, it is more specific due to its unique arrangement of atoms in the molecule.
