Question 27

A chemist considers using molecules A and B as starting materials.

MoleculeType of moleculeStructural formula
AalcoholCH3CH2OH\text{CH}_3\text{CH}_2\text{OH}CH3​CH2​OH
Bcarboxylic acidCH3CH2COOH\text{CH}_3\text{CH}_2\text{COOH}CH3​CH2​COOH

A hydroxyl group can react with a carboxyl group. A covalent link forms and water is released.

Many molecules of A and B are mixed. Suggest why the reaction does not build a long polymer chain.
