The molecular formula, the line formula, and the condensed formula for the normal alkane having12 carbon atoms are to be determined. Concept introduction: A given hydrocarbon can be represented using different formulas. It can be represented using structural formula, structural diagram, line formula, condensed formula, or Lewis diagram. Lewis diagram is the representation of the molecule or ion. It shows the bonding between the atoms and also shows the unshared pairs of electrons on an atom if any. The structural formula or structural diagram is nothing but Lewis structure without unshared pairs of electrons. Line formula is the shorthand representation of the Lewis diagram, in which the bond between the parent chain carbon and atoms or other branches from the chain are not shown. Clubbing of CH 2 units together in a line formula gives condensed formula.
