1. What type of intermolecular force is predominant in the following two compounds? H3C -C-CH3 H3C- CH-CH (3 points) 2. Hydrazine (NH2NH2), hydrogen peroxide (HooH), and water (H20) all have higher boiling points in comparison with other substances of comparable molecular weights. What structural property do these substances have in common, and how might that account for (4 points) their high boiling points? 3.

VSEPR Objective : This lab is to study the shape and polarity of molecules using VSEPR theory with emphasis on sigma bonds (Part 1) and pi bonds and resonance (Part 2) Procedures: Nothing to do before the lab. We are making the models together in class. Prelab Questions : PART 1: (PL1) Draw the Lewis dot structure of each compound (as having covalent bonds). (a) BeH2 (b) BH3 (c) GeH2 (d) CH4 (e) NH3 (f) H2O (g) PCl5 (h)...
