I was not expecting that awnser. It depends on the reaction I am doing. Wow. I'am doing many reactions. There are many.
-Alchols recting with acidified di chromate
-Alchols reacting with hot sulfuric acid
-oxidation and reaction reactions
-acetic acid reactions etc
The way I understand is that the product that that used to be a reactant and had the nucluphile has to have no formal charges but evreything else that was formed by leaving groups can have a formal charge. How far away I am from being correct
