The first four carboxylic acids mix with water in all proportions. The solubility of alcohols in water decreases with increasing carbon chain length as the non-polar contribution to the molecule becomes more important. (a) Ethanol, butane, diethyl ether (b) 1-Hexanol, 1,2-hexanediol, hexane. 1 decade ago . Books. With increase in the number of hydroxyl groups along a carbon chain will increase the polar nature of the compound. This high solubility of water can be explained by hydrogen bonding (the same reason as for alcohols). The hydroxyl group (–OH) is very polar, and so many alcohols are soluble in water, which is also very polar. Diols are much more soluble in water than the alcohols as they have a higher solubility in water. Arrange the compounds in each set in order of decreasing solubility in water.
