2.2 Intramolecular Force and Potential Energy Diagrams

Multiple Choice

What type of bond is present in the Cl₂ molecule?

• Ionic

• Polar Covalent

• Non-polar Covalent

• Metallic

Open Ended

Cl₂  reacts with the element  Sr  to form an ionic compound. Based on periodic properties, identify a molecule,  X₂ , that is likely to react with  Sr  in a way similar to how  Cl₂  reacts with  Sr . Justify your choice.

Draw

A graph of potential energy vs internuclear distance for 2 Cl atoms is given. On the graph sketch the curve that corresponds to potential energy vs intermolecular distance for two BR atoms.
