Alkanols have the general molecular formula CnH2n+1OH, where n is the number of carbon atoms in the molecule. An alkanol is an organic compound that contains a hydroxyl group (-OH) attached to an alkane, which is a hydrocarbon chain composed of only carbon and hydrogen atoms.
It is important to note that the molecular formula for an alkanol will vary depending on the number of carbon atoms in the molecule. For example, methanol (CH3OH) has one carbon atom, while ethanol (C2H5OH) has two carbon atoms, and so on.
