I have been having trouble figuring out how to do problems 8-10 in the attachment below. I completed the problems, but I would like to make sure that I have the correct answers and that I understand the solutions to the problems.
This solution provides a detailed description of a number of concepts related to chemical bonding. Included is a description of stable molecules, an explanation of p-orbitals and d-orbitals and their involvement in sigma and pi bonds and their interactions. There is also a description of W-C bonds, and an explanation of formulas for flouroanions/fluorides and oxoanions/oxides and their Lewis structure, shape, and bonds angles.
