Explanation:
A chemical formula used for a series of compounds that differ from each other by a constant unit is called a general formula. It generates a homologous series of chemical formulas. For example, alcohols may be represented by the formula CnH(2n + 1)OH (n ≥ 1), giving the homologs methanol, ethanol, propanol for n=1–3.
