400
What is the difference between IR and Raman active molecules?
IR active molecules have a double bond, free electrons, and have asymmetric symmetry.
Raman active molecules have symmetric stretching and are more polarizable.
400
What are the elements on the zig zag line called?
Metalloids
500
Rank the following in order of least acidic to most acidic and explain why this trend occurs:
- HBrO, HBrO2, HBrO3, HBrO4
HBrO < HBrO2 < HBrO3 < HBrO4
The electron density shifts to the oxygens making it easier to deprotonate the H.
