29 October Announcements Exam scores and ALEKS posted this afternoon Model assignment Focus on intermolecular forces Form on RamCT Specific examples on form to help Due beginning of class, Wednesday, 11 / 3 Hydrogen bonding Special type of dipole-dipole force H bonded to N, O, or F Why N, O or F? Highly electronegative with lone pairs Typically drawn to show connection between δ+ H and the lone pair Strongest dipole-dipole force Larger mass makes boiling point go up because you’re trying to separate two large things Larger polarizability makes boiling point higher because instantaneous dipoles occur more often Intermolecular forces review London dispersion forces Most common Typically involv
