Structural Formula of Sodium Butanoate: Draw The Structure Of Sodium Butanoate
Sodium butanoate has the structural formula CH3CH2CH2COONa. It is an ionic compound consisting of a sodium cation (Na+) and a butanoate anion (CH3CH2CH2COO-). The butanoate anion is a carboxylate anion, which is a conjugate base of a carboxylic acid. In this case, the carboxylic acid is butanoic acid (CH3CH2CH2COOH).The
carbon atoms in the butanoate anion are arranged in a tetrahedral shape, with the oxygen atoms of the carboxylate group occupying two of the tetrahedral positions. The sodium cation is located near the oxygen atoms of the carboxylate group, forming an ionic bond.
The overall molecular shape of sodium butanoate is therefore tetrahedral.
Functional Groups in Sodium Butanoate
Sodium butanoate contains two functional groups: a carboxylate group and an alkyl group.The carboxylate group is a functional group that consists of a carbon atom double-bonded to an oxygen atom and single-bonded to a hydroxyl group. The carboxylate group is a polar functional group that can form hydrogen bonds with other molecules.The
alkyl group is a functional group that consists of a carbon atom chain. The alkyl group in sodium butanoate is a butyl group, which consists of four carbon atoms. The alkyl group is a nonpolar functional group that is hydrophobic.
