Honors Chemistry Unit 11 - Intermolecular Forces Study Guide with Complete Solutions Forces between atoms in a compound are ______________ ______. - Answer️️ - intramolecular forces Forces that act between molecules are ______________ ______. - Answer️️ - intermolecular forces _____ _________ have very strong bonds (attractive forces) so they have high melting points and boiling points. - Answer️️ -ionic compounds ________ _________ have lower melting and boiling points because covalent bonds are not as strong as ionic bonds. - Answer️️ -covalent compounds Generally, intermolecular forces are much ______ than intramolecular forces. - Answer️️ -weaker We can use _________________ to predict what kind of bond will form. - Answer️️ - electronegativity _____ _________ are like a battery, they have a positive and a negative end (like two poles of a planet or a magnet); the ends are opposite of each other. - Answer️️ -polar molecules A ______-______ _____ happens between the partial charges of polar molecules. - Answer️️ -dipole-dipole force ©SOPHIABENNETT 2024/2025 9:45 AM Page | 2 The ____ polar the molecules are, the stronger the dipole-dipole forces between them, and thus, the higher the boiling point. - Answer️️ -more ________ _____ involve the attraction between polar molecules that contain hydrogen and molecules that have N-H, O-H, or F-H bonds. - Answer️️ -hydrogen bonds ________ _____ are very strong because hydrogen atoms are small and very polar (a large difference in electronegativity between atoms). - Answer️️ -hydrogen bonds Water has unique properties because of all the strong ________ _____. - Answer️️ - hydrogen bonds ______ __________ ______ are nonpolar molecules, like F₂, which can be
