Problems and exercisesPhysical and Bond Properties
1. Boiling point
Acetyl chloride (mass 78.5) boils at 51 °C and acetic acid (mass 60) at 118 °C. Explain.
2. Resonance
The C–Cl bond of acetyl chloride (1.743 Å) is almost the same as in chloromethane (1.741 Å). What does this say about the third resonance form?
