Question

benzonoic acid dissolved in benzene will show a molecular weight of

Answer 1

Benzonic acid dissolved in benzene is found to have molecular mass double its normal molecular mass.

This is explained by the fact that benzoic forms dimer in benzene solution due to hydrogen bonding

Normal Molecular weight of benzoic acid is 122

Observed molecular mass is 244

Benzonic acid dissolved in benzene is found to have molecular mass double its normal molecular mass.

This is explained by the fact that benzoic forms dimer in benzene solution due to hydrogen bonding

Normal Molecular weight of benzoic acid is 122

Observed molecular mass is 244
