London dispersion forces - Study guides, Class notes & Summaries

Intermolecular forces and how they affect physical properties /purification techniques: dipole-dipole, electrostatic, hydrogen, ion, london, - Answer-*dipole-dipole*: polar covalent molecules such as aldehydes and ketones. positive and negative end. polar molecules must be close together for force to be significant. weaker than ion-dipole forces; increase with polarity of molecule. *electrostatic*: occur between charged species, cations and anions, and are responsible for very high MP and B...

intermolecular forces - Answer forces of attraction between molecules IM forces are weaker or stronger than covalent or ionic bonds? - Answer weaker the stronger the IM forces - Answer the higher the boiling point ion-dipole forces - Answer electrical attractions that exist between an ion and polar molecules dipole-dipole forces - Answer electrical attractions that exist between polar molecules london dispersion forces - Answer electrical attractions resulting from a t...

MCAT Organic Chemistry Written Exam. Electrostatic Forces - CORRECT ANSWER The attractive force between electrons and the nuclei that is responsible for all molecular bonds. Coordinate Covalent Bond - CORRECT ANSWER One nucleus donates both of the electrons in the bond. Hybridization - CORRECT ANSWER sp - 180° - linear sp2 - 120° - trigonal planar sp3 - 109.5° - tetrahedral, pyramidal, or bent dsp3 - 90°, 120° - trigonal-bipyramidal, seesaw, t-shaped, linear d2sp3 - 9...

intermolecular forces correct answer: the various forces of attraction that may exist between the atoms and molecules of a substance due to electrostatic phenomena kinetic energies correct answer: the energy required to overcome the attractive forces and thus increase the distance between particles Intramolecular forces correct answer: within the molecule that keep the molecule together Intermolecular forces correct answer: attractions between molecules, which determine many of the ...

CEM 141 Final Exam Questions and Answers Already Passed Why are alpha particles deflected by the nucleus? Because both the alpha particles and the nucleus are positively charged and so the alpha particle is repelled. Is this statement (Dalton's Theory) true or false and why? "All atoms of an element are identical and have the same mass and properties." False. Atoms of the same element can have different numbers of neutrons. What is the evidence that electrons are subatomic pa...
