CEM 142 Recitation 1 KEY IMF Review 1a. Draw 3 molecules of CH 3 CH 2 CH 2 CH 3 (butane) in the liquid state showing the strongest interactions that are present between the molecules. 1b. What type of interaction did you show in your picture? Identify the important features of the interaction and how they were depicted in your picture. Make sure your interaction is labeled. Revise your picture if necessary. London dispersion forces are temporary interactions between an instantaneous dipole and the subsequently induced dipole. Therefore, the dipoles should be labeled as such. These temporary dipoles should be indicated on both electron clouds using partial positives and partial negatives. The molecules should be lined up so that the partial positive end of one is interacting with the partial negative end of another molecule. For clarity, the LDF interaction is labeled, and an arrow is used to specify the place where the interaction occurs. 1c. Are there any other intermolecular forces present in liquid CH 3 CH 2 CH 2 CH 3 ? If so, list them below. none
2a. Draw 3 molecules of (CH 3 ) 3 N (trimethylamine) in the liquid state showing the strongest interactions that are present between the molecules. 2b. What type of interaction did you show in your picture? Identify the important features of the interaction and how they were depicted in your picture. Make sure your interaction is labeled. Revise your picture if necessary. Dipole-dipole is an interaction between the molecular dipoles of two polar molecules. Therefore, showing the 3D-shape of the molecule and using a molecular dipole arrow is the best way to indicate the overall polarity. The molecules should then be ordered in a way that clearly indicates that the interaction is taking place between the positive end of one molecule and the negative end of another. For clarity, the dipole-dipole interaction is labeled, and an arrow is used to specify the place where the interaction occurs. 2c. Are there any other intermolecular forces present in liquid (CH 3 ) 3 N? If so, list them below. LDFs
