UCF Chem 2 Exam 1 Questions With 100% Correct Answers 2024

What is a covalent bond? - Answer A covalent bond is a chemical bond that occurs when one or more electron is shared between the atoms. all intermolecular forces are much weaker than covalent bonds. True or False - Answer True. What are three types of intermolecular forces - Answer London dispersion, dipole-dipole, hydrogen bonding What are London dispersion forces? - Answer The intermolecular attractions resulting from the constant motion of electrons. What is a dipole-dipol...

Hydrogen Bonds correct answer: - Specific type of dipole-dipole interaction - MUST have a H covalently bonded to F O or N Dipole-Dipole correct answer: - Attractions between polar molecules - Weaker than covalent bonds - Stronger the dipole moment, the boiling point gets larger Dispersion Forces correct answer: - Everything has these - Attractions arise from movement - Short-lived interaction; Very weak - Contribute to ALL intermolecular forces London Forces depend on: ...

intermolecular forces correct answers forces that hold molecules to other molecules (not bonds within molecules) ion-ion interaction correct answers occurs between ions, with opposite charges attracting and like charges repelling ion-dipole interaction correct answers occur between ions and polar molecules, where the ion is attracted or repelled to a partial charge in the polar molecules (includes interactions between water and dissolved ions) dipole-dipole interaction correct answers o...

Intermolecular Forces - Answer Forces of attraction between molecules ion-Dipole - Answer Forces of attraction between an ion and a polar molecule. Na+ & Cl- Dipole-Dipole - Answer Forces between the negative end of one polar molecule and the positive end of one polar molecule and the positive end of another polar molecule. Hydrogen Bonding - Answer Forces between a Hydrogen and a Fluorine, Oxygen, or Nitrogen London Dispersion - Answer Forces exist between all species. Wea...
