Select the compounds that are more likely to be a liquid at room temperature (as opposed to a gas). a) HF b) H₂O c) C₂H6 d) CH₂OH e) CH4

1. The phrase "Structure influences properties" is used in this course. Describe what this phrase means for you and provide at least 1 example. 2. Using the Lewis structure for each substance below, predict the hybridization for the central atom and shape of each molecule a) CF, b) PH3 c) CS2 3. The prediction of melting point rank can be useful when discussing the different applications of substances. Rank the following 4 substances from highest to lowest melting point. Include your reasoning for your rank based on intermolecular forces of attraction and support your reasoning with Lewis structures. Ammonia, NH3, Magnesium oxide, MgO, Sodium oxide, Na,0, Carbon dioxide, CO2
