what is general molecular formula. Molecular formula A chemical formula that shows the total number and kinds of atoms in a molecule but not their structural arrangement. The general formula for rings is C n H 2n.
For an alkane for example the general formula is C n H 2n2. The chemical formula is C10H18. The atoms are depicted by their symbols which are shown in the periodic table.
Other common disaccharides include lactose maltose and trehalose.
Moreover we should write the numbers of atoms as subscripts. The general molecular formula for alkanes is CnH2n2. And this is the correct chemical formula for our example monosaccharide glucose. For example the molecular formula of aspirin is C9H8O4.
