Re: Numbering the Carbon

What I do is, I right them out both ways and then I add the number of Carbons and chose the one with the least. For example, 1+3 is 4 while 5+3 is 8. So the first one was the correct one because 4 is smaller than 8. Hopefully that helps a little.

Re: Intermediates vs. Transition States

Intermediate states have fully formed bonds while transition states have partially formed bonds.

Re: VSEPR and Polarity

You first draw the lewis dot structure of the compound. Then see where there are any lone pairs. If there are lone pairs and others have bonds then it is polar but if it's all equal and as they pull, they cancel each other out then it is non-polar.

Re: Quantum Numbers

N equals the energy level.
L is the subshell designation, L= n-1
Ml tells us the number of orbitals, -L to 0 to +L,
Ms tells us whether the spin is up or down, +1/2 is up and -1/2 is down
Another thing to remember is: L=0 is s-subshell, L=1 is p-subshell, L=2 is d-subshell, L=3 is f-subshell.

Re: How do you go from meter to nanometer? [ENDORSED]

1X10^-9 meters is the same a 1 nanometer. The conversion is quite simple. Example: 3X10^-9 meters is 3 nanometers or 450nm is 450X10^-9m.
