When you are naming alkenes, does the number where the double bond is go in the front, or after the but or another prefix. Thank you.

Re: Naming [ENDORSED]

When you add the numbers to the name, I know that the position is the first number, but what is the number after the name? Ex. 3-methyl-5,5-pentanehexane or whatever it would be. Thank you.

For the equilibrium constant Kp, the equation is Kp= Kc(RT)^delta n. For delta n, do you use all of the moles in the reaction (solids, liquids, and gases) or just count the moles for the gases?
