WebWhen the hydrocarbon chain is short, the alcohol is soluble in water. There is no limit on the amount of methanol (CH 3 OH) and ethanol (CH 3 CH 2 OH), for example, that can dissolve in a given quantity of water. As the hydrocarbon chain becomes longer, the alcohol becomes less soluble in water, as shown in the table below. WebThe solubility of alcohol in water decreases with increasing size (number of carbon atoms). For example, methanol and ethanol are very soluble in water whereas octanol is insoluble in water. Typically, hydrocarbons with more than 7 carbons are considered insoluble in water. Polarity and solubility in water also differ between alcohol isomers.
