Benzene is a non-polar solvent and therefore does not react with acetic acid.
Acetic acid due to the presence of electronegativity difference between Oxygen and Hydrogen will form Intermolecular Hydrogen bond with another Acetic Acid molecular and undergoes dimerisation.
Why is acetic acid dimer?
Carboxylic acids form dimers by hydrogen bonding of the acidic hydrogen and the carbonyl oxygen when anhydrous. For example, acetic acid forms a dimer in the gas phase, where the monomer units are held together by hydrogen bonds. Under special conditions, most OH-containing molecules form dimers, e.g. the water dimer.
Why most carboxylic acid exist as dimer?
it exists as dimer because it can form a strong hydrogen bond among its own molecules and to greater extent . Carboxylic acids exist as dimer with two molecules held together by hydrogen bonding,As we see the carboxylic acid in vinegar can hydrogen bond to each other, and their bonding is to greater extent.
What is dimer formation?
A protein homodimer is formed by two identical proteins. A protein heterodimer is formed by two different proteins. Most protein dimers in biochemistry are not connected by covalent bonds. An example of a non-covalent heterodimer is the enzyme reverse transcriptase, which is composed of two different amino acid chains.
What is a dimer in organic chemistry?
Illustrated Glossary of Organic Chemistry – Dimer. Dimer: A structure containing two identical or similar units. Gly-Gly is a dipeptide dimer in which the two amino acid residues are identical (both are glycine). The two units comprising this dimer are attached via a covalent bond.
