Question

What would happen if water was added to a reaction mixture before letting it cool

Answer 1

It would help if we knew what was being added to what. And what is the solvent in the reaction mixture.

Answer 2

The water is being added to benzhydrol, propanol and sulfuric acid which is the catalyst in a separatory funnel after the reaction mixture is heated at refulx for 25 minutes. It is an SN2 reaction so the solvent is THF

Answer 3

I was wrong. It doesn't help.
