Depicting molecules and ions with Lewis Structures (Section 10.1) — You should know how to draw the Lewis structure for any molecule if given the molecular formula of the compound. You need to know how to and when to apply concepts such as octet rule, resonance, formal charges. 2. Valence-shell electron pair repulsion (VSEPR) theory and molecular shape (Section 10.2) — Be able to predict the electronic geometry of any compound by first drawing the Lewis structure from the molecular formula. You can then categorize the geometry as linear, trigonal planar, tetrahedral, trigonal bipyramidal, octahedral Also, be able to predict molecular geometry (shape) by first determing the Lewis structure and the electronic geometry and then using the following to describe its shape; linear, bent, trigonal planar, tetrahedral, trigonal pyramidal, trigonal bipyramidal, square planar, square pyramidal, octahedral. 3. Molecular shape and molecular polarity (Section 10.3) — Predict whether a molecule has a dipole moment by identifying polar bonds and then determine the net dipole of the molecule based on its polar bonds and molecular geometry.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
