Document Summary

Blend of chemistry and biochemistry to show the connection between the two. Pretty much the same format for discussions and lectures. Not as many mathematical equations and solving. Carbon and hydrogen- not very electronegative so they are weak forces. Just have carbon and hydrogen so they are nonpolar. They can"t form ionic bonds because too many ve to loss and gain. 2s and 2p which are a spherical shape and a dumb-bell shaped orbital. Tetrahedral geometry with a bond angle of 109. 5 degrees. Dashed line is the one going back. Thick filled in line is the one that is coming forward. In order to indicate that this carbon structure is 3-dimensional use this notation: The three 2p orbital covers the three axis. Larger lobe that points to the ends of the tetrahedral. Combine and then redistribute take orbitals and then rearrange to share the electron density. Sp3 hybridization- an s and three p"s.
