Solution Preview

A) Only covalent bonds have hybridized orbitals, so no hybridization for SrCl2
B) NO2 has a double bond with one of the oxygens, so sp2 hybridized
C) COF2 ...

Solution Summary

In this solution we consider two separate concepts. First, we determine the orbital hybridization of 5 different covalent compounds and predict their molecular structure. Then we work on three different problems dealing with the makeup of solutions. First we demonstrate the concept of a % w/w solution and solve, and then there are two dilution problems we consider with the help of a specific formula. Don't miss this one if you are having trouble with any of these concepts!
