Problems and exercisesPhysical and Bond Properties
1. Anhydride or acid
Acetic anhydride (mass 102) boils at 140 °C and acetic acid (mass 60) at 118 °C. Is this consistent with the acid forming dimers?
2. Resonance
Why is the resonance of the central oxygen with each carbonyl weaker in an anhydride than in an ester?
