Determine the Bond Type (Electronegativities) Sodium and Sulfur Chlorine and Oxygen Phosphorus and Copper Oxygen and Oxygen Bromine and Calcium Hydrogen and Nitrogen

Answers Na (0.9) and S (2.5): 1.6 difference  polar covalent Cl (3.16) and O (3.44): 0.28 difference  non-polar covalent P (2.1) and Cu (1.9): 0.2 difference  non-polar covalent

Answers O (3.5) and O (3.5): 0.0 difference  non-polar covalent Br (2.8) and Ca (1.0): 1.8 difference  ionic H (2.1) and N (3.0): 0.9 difference  polar covalent

Intermolecular Forces If simple, diatomic molecules composed of the previously mentioned bonds were in a solution, what type of intermolecular forces would lead them to attract to each other? Sodium and Sulfur Chlorine and Oxygen Phosphorus and Copper Oxygen and Oxygen Bromine and Calcium Hydrogen and Nitrogen

Intermolecular Forces Sodium and Sulfur  polar covalent  dipole forces Chlorine and Oxygen  polar covalent  dipole forces Phosphorus and Copper  non-polar covalent  london forces

Intermolecular Forces Oxygen and Oxygen  non-polar covalent  london forces Bromine and Calcium  ionic  ionic bond Hydrogen and Nitrogen  polar covalent  hydrogen bonds (type of dipole force, hydrogen interacting with F, N, or O)
