1) A molecule of chloromethane (CH3Cl) has the same shape as a molecule of methane (CH4). However, methane has a boiling point of -164 C while chloromethane has a boiling point of 62 C. a. Draw the Lewis diagram for each molecule b. Label each molecule as polar or non-polar. c. Explain the difference in boiling points based on what you know about intermolecular forces. (HINT: Be specific about the intermolecular forces that are present!)
2) Complete the table. Chemical Type of Bonding Chemical Lewis Diagram AEN Formula (Ionic/Polar

3) Calculate the atomic mass of silicon. The three silicon isotopes have atomic masses and relative
abundances of 27.9769 amu (92.2297%), 28.9765 amu (4.6832%) and 29.9738 amu (3.0872%).
