Trimethyl carboxyllic acid
WebCarboxylic acid. In organic chemistry, a carboxylic acid is an organic acid that contains a carboxyl group ( C (=O)OH) [1] attached to an R-group. The general formula of a carboxylic acid is R−COOH or R−CO2H, with R referring to the alkyl, alkenyl, aryl, or other group. Carboxylic acids occur widely. Important examples include the amino ...
