WebPHYSICAL PROPERTIES OF ALCOHOL Alcohol molecule, with a general formula of R-OH, have both polar and non-polar character. The hydroxyl group (-OH) present is polar, and the alkyl (R) group present is non-polar. The physical properties of an alcohol depend on whether the polar or the non-polar portion of its structure “dominates”.
