Based on whether each molecule is Ionic, Polar Covalent, or Nonpolar Covalent, put it in order from highest melting point to lowest melting Point. The Formula Weights or Molecular weights are given to the right in g/mol.
Nitrogen Gas (28)
Beryllium Oxide (25)
Carbon Monoxide (28)
Categorize each of the following compounds, considering their molecular geometry and the difference between their electronegativities. (Ionic bonds form when the difference is greater than 1.7-2.1, depending on the pair of elements, polar bonds form when the difference is 0.4 unless the geometry cancels out the partial charges.

Nitrogen Trihydride (Trigonal Pyramidal)
Dihydrogen Oxide (Bent)
Carbon Dioxide (Linear)
Hydrogen Chloride (Linear)
Magnesium Fluoride (Crystalline)
Carbon Tetrachloride (Tetrahedral)
Sulfur Trioxide (Trigonal Planar)
Ionic (Highest Melting Point)
Polar Covalent
Nonpolar Covalent (Lowest Melting Point)
Based on whether each molecule is Ionic, Polar Covalent, or Nonpolar Covalent, match it with its melting point. The Formula Weights or Molecular weights are given to the right in g/mol. There is one of each type of compound.
