Dr. Sereda, I am mostly understanding Huckel’s rule, however, I am unsure of what integer to plug in. I understand that it can be 0, 1, 2, 3, etc.. but how do you know when to plug in 0 for n, versus when to plug in 1 or 2? (If N is number of electrons, the integer n can be found from the equation: N=4n+2 or n=(N-2)/4  - GS).
