Organics in Water Chemical Principles 12. Intermolecular Forces depend on dipole moments and hydrogen bonding 13.
Catalysts reduce the activation energy necesary for a process to occur.
Each representation offers advantages and disadvantages - each teaches us something about the individual molecules and about the mass of molecules in the bulk substance. See MTBE as a three-dimensional, manipulable wireframe figure . And as you move your mouse across this image, you see the molecule turn so that you can envision all its spacial characteristics. To understand this section fully, you need to be familiar with electronic structure, sigma and pi electrons and the principles of catalysis and the properties of liquids and how they vary with intermolecular forces. It is prepared by an addition reaction between two of the most common organic substances, isbutylene and methanol.
