Covalent Lewis Structures, Polarity and
Molecular Shape of Structure
Draw the Lewis structure for the formula given in the box below the formula. Then determine the
polarity of the molecule by finding the electronegativity difference. Use the molecular geometry chart
found on Schoology to determine the name of the molecular shape (bent, tetrahedral, etc.) and then draw
the molecular shape using the rules found below the table.
