Unformatted text preview: The shape of the p orbital is derived from the spectroscopic lines being principal, hence p for principal. It looks like a dumbbell and is said to be peripheral shaped. B. What is an antibonding molecular orbital? An antibonding molecular orbital is the overlap of orbitals of other atoms that are not in the correct phases. They also have a higher energy than they did in a normal bonding molecular orbital. 4. (3 pts) Indicate if the non-hydrogen atoms below have a 0, -1 or +1 formal charge. All lone pairs have been drawn in. O C C O CH 3 CH 3 : .. .. : : A B C D E F A. -1 B. C. +1 D. E. F....
