A solution is prepared by dissolving 27.0 g urea, (NH2)2CO, in 150.0 g water. Calculate the boiling point of the solution. Urea is a nonelectrolyte.
CHEM 112 (Wk 2) Formal Charge, hybridization, resonance, periodic trends Throughout these notes you can refer to the following tables… Table 10.1 p.325 Table 10.2 p.331 Table 7.4 VSPER theory: Purely geometrical model V: valence S: shell E: electrons P: pairs R: repulsion Electrons will spread out as far as possible in 3-D space to minimize interaction between them. Hybridization Chemical way to talk about geometry The d orbital is introduced for elements row 3 and below. The following chart is for compounds without any lone pairs attached to the central atom A: Central atom B: Bonding atoms In this case we ae naming compounds consisting of only two atoms (A & B) Compound CO 2 BF3
