What is the colour of a leaf when the chlorophyll is removed?
As we know, chlorophyll is what causes the leaf to appear green. From what I know there is a very specific way to extract chlorophyll from leaves. 1. Boil the leaf to kill the cells and arrest all the chemical activity, this also makes it permeable to alcohol and iodine later on. 2. Submerge the leaf in alcohol (ethanol) which is kept in test tube. 3. Put the test tube into the boiling beaker in step one so the alcohol is boiled alone with the leaf in it. The chlorophyll should be extracted as the alcohol turn green. As for the leafs, they usually only appears lighter than it is originally is, which is VERY light green. I have never seen a leaf with absolutely no chlorophyll so can't tell you right here. WARNING: Alcohol in gas form is highly flammable.
How do you separate alcohol from fermented sugar by the process of evaporation and condensation?
The process in which alcohol is separated from fermented sugar is called distillation. In this process, the mixture is heated to the boiling point of the alcohol and the alcohol vaporizes and is then condensed back into a liquid inside of a condenser coil, and then is drawn off into a different container.

Why did the alcohol turned green when the leaf was put into it?
