Document Summary

Organic chemistry midterm #2: (consituional and conformaional isomerism) Sp3 hybridized meaning it has 109. 5 degree angles. Eclipsed conformaion: atoms are directly behind one another, has maximum energy, molecules are very close to each other, want to unwind to a staggered conformaion. Staggered conformaion: atoms are not behind one another, has minimum energy, has a dihedral angle of 0 degrees (way of saying how staggered you are), electron clouds are all negaive; that"s why they are away from each other (staggered) Show these conformaions through the usage of newman projecions. Butane chain: four carbons, use 2nd carbon as front, 3rd carbon is in the front, replace the irst and fourth carbon with ch3. When drawing the front carbon, its always the irst on the lef. Butane ends up being a staggered newman projecion, all groups have electron clouds, ch3 biggest electron cloud, want to be the farthest away from each other as they can.
