Hydrocyanic acid reacts with potassium hydroxide forms potassium cyanide and water. The LCC contains four carbon atoms; the compound is therefore named as a substituted butyric (or butanoic) acid. Ester molecules can engage in hydrogen bonding with water, so esters of low molar mass are therefore somewhat soluble in water. 1. The simplest carboxylic acid, formic acid (HCOOH), was first obtained by the distillation of ants (Latin formica, meaning ant). The LCC contains four carbon atoms; the compound is therefore named as a substituted butyric (or butanoic) acid. Propanoic acid (C 2 H 5 COOH) is described as a weak acid. Carboxylic acids have high boiling points compared to other substances of comparable molar mass. the neutralisation reaction forms a metal salt and water.
