Document Summary

The best way to learn is the lecture, and lecture slides/notes. Covalent bonds determined by polarity and charge distribution. Only hydrogen and carbon determined in models. Most common form of glucose is cyclic. Certain molecules with particular formula can have different types of structure. If you have double bond between the two carbons, it is rigid. Cis: two xs on the same side. Trans: two xs are on opposite sides. Should be able to recognize which type of isomer. Can have single carbon as the center of four groups. One is right handed one is left handed, so arrangement around a certain central molecule can be slightly different (like mirroring) Glucose: has two enantiomer, one is biologically active and the other is not. Ibuprofen: two isomers: s-ibuprofen is effective, but r-ibuprofen is not. Polar because the electrons spend more time with electronegative oxygen. Donates proton, dissociates and comes free in water.
