Name ___________________________________ CHM 11200 Spring 2023 Activities and Explorations: 10 points, Due Sunday Jan. 22, 11:59 PM Claim, Evidence, Reasoning: Boiling point Instructions: Upload your work on this page to Brightspace by typing or writing your responses and saving the file and uploading that file as a pdf. You can also take pictures of your written work and paste them in! Learning Objectives 11.2 Intermolecular Forces  Identify the intermolecular force(s) present between the same molecules and between different molecules – identify the strongest intermolecular forces in these interactions.  Interpret molecular-level models/images in terms of the intermolecular interactions present.  Identify relative boiling points and/or vapor pressure of molecules using Lewis structures, surface area of the molecule, and intermolecular interactions. 11.3 Properties of Liquids  Compare molecules based upon relative strength of intermolecular forces as well as surface tension, viscosity, vapor pressure, boiling point, and melting point. Goal: Using intermolecular forces determine which compound has the highest boiling point. The Lewis structures and chemical formulas for butane, acetone, and acetic acid are given below. Butane, C 4 H 10 Acetone, C 3 H 6 O Acetic acid, CH 3 COOH 58.12 g/mol 58.08 g/mol 60.05 g/mol 1. Evidence: a. (3 pts.) What intermolecular forces (IMFs) exist in a pure sample of each compound? i. Butane ______London dispersion forces_____ ii. Acetone _____Dipole-dipole, London dispersion forces___ iii. Acetic Acid _______Hydrogen bonding, Dipole-dipole, and London Dispersion forces________________________ b. (1 pt) Which IMF is the strongest and which is the weakest? Butane is the weakest and Acetic acid is the strongest.

Name ___________________________________ CHM 11200 Spring 2023 c. (1 pt) How do those IMFs influence the boiling point of a compound? (Hint: What is the relationship between IMFs and boiling point?) As the strength of the IMFs increases, the boiling point increases. 2. Claim (1 pt): Which compound has the highest boiling point ? (write your claim here as a sentence) The Acetic Acid has the highest boiling point. 3. Reasoning (4 pts) : (Connect your evidence in #1 to your claim in #2 and use concepts and information from class, lab, recitation, SI, etc.) (2 pts – relate IMFs to boiling point and ordering of compounds) (2 pts. – relate energy, boiling, and IMFs) Acetic acid has the highest boiling point. The strength of the acetic acid is the strongest compared to the others because it not only has Dipole-dipole and London dispersion, but it also has hydrogen bonding. Hydrogen bonding is typically stronger than Dipole-dipole and London dispersion forces. The stronger the IMFs is, the higher the boiling point will be. Hydrogen bonding will also have a high difference in electrostatic behavior and more polarity causing it to have more energy than the others. More energy will also make it to have strong IMFs, causing a high boiling point. Butane will be the weakest and have the lowest boiling point with London dispersion forces. Acetic acid will be the strongest with the highest boiling point and Acetone will be in the middle of the two molecules with Dipole-dipole and London dispersion forces.
