Intramolecular Force and Potential Energy Practice Test

A qualitative potential energy curve for a diatomic molecule shows two possible bonds: Bond X has a deeper minimum in potential energy than Bond Y. Which bond has the greater bond strength?

Two potential energy curves are shown conceptually for diatomic molecules X and Y. Molecule X has a deeper potential energy well and a shorter equilibrium distance than molecule Y. Which molecule has the lower potential energy at equilibrium and the stronger bond?
