In this lab, students will use a stainless steel temperature sensor to determine the effects of molecular size and shape on the strength of intermolecular forces for different alcohols within the same homologous series and between isomeric pairs. types of molecules (i. comparing an alkane with a larger alkane) will also increase the in one molecule and a partially electronegative atom in another, and dipole-dipole interactions, Its also possible to use Labster without an LMS. Examples of bulk properties of substances could include the melting point and boiling point, vapor pressure, and surface tension. H*2P0P034R04R(J For example, you have London Dispersion forces between two molecules of water in a setting but you can't have it when you only have one water molecule. Intermolecular Forces. Be sure to emphasize that "hydrogen bonding" is an intermolecular force, not a bond/an intramolecular force, like ionic, covalent, or metallic bonds. Reported resources will be reviewed by our team.

Emphasis is on understanding the strengths of forces between particles, not on naming specific intermolecular forces (such as dipole-dipole). In this simulation, you will learn about the intermolecular forces caused by temporary molecular dipoles, permanent molecular dipoles, and hydrogen bonding. Intermolecular forces are responsible for most of the physical and chemical properties of matter. The former is termed an intramolecular attraction while the latter is termed an intermolecular attraction. %%EOF % In this video Paul Andersen explains how intermolecular forces differ from intramolecular forces.
