22Dimethylhexanoic
2,2-Dimethylhexanoic acid is a branched-chain carboxylic acid. Its chemical formula is C8H16O2. The structure consists of a six-carbon chain (hexane) with two methyl groups attached to the second carbon atom. The presence of these methyl groups makes it a tertiary carboxylic acid. It is an isomer of other octanoic acids, such as n-octanoic acid and 3,5,5-trimethylhexanoic acid.
Like other carboxylic acids, 2,2-dimethylhexanoic acid exhibits acidic properties due to the carboxyl group (-COOH). It
