Glucose is one of the important carbohydrates in the field of bimolecular chemistry. Glucose has a general formula which is; (C6H12O6), with this formula, it renders glucose to be called hexose sugar. In a general properties reference to glucose it pose asymmetrical carbon. Chiral carbon
Asymmetrical carbon: A carbon in which four dissimilar atom is attached to it carbon chains, is said to be asymmetric carbon, see diagram bellow;
In other to determine the possible isomer of any compound the number of asymmetric carbon atom, of the molecule must be first consider.
According to Van Hoff’s of (n) number: he said the number of possible isomer of any given compound depend on the molecule it posses. In this rule we can observed that the possibility of any isomerism depend on the asymmetrical carbon it poses.
Also look at Van Hoff’s of (n) number 2: he said there is equal possibility of two isomer of that compound, where n represent the number of asymmetrical carbon atom in the compound.
