after doing an aldol condensation, I have seen problems where the alcohol in aldol product would remain there, and some cases where the alcohol would be dehydrated...now how does one know if the alcohol becomes dehydrated?

The alcohol becomes dehydrated if the aldol product is heated, forming an alkene through an E1 reaction. And since you will get water as a product along with your new double bond, it is termed a condensation. Thus, aldol condensation. Hope this helped!

I read in the acs review book that it typically dehydrates under heat or if the product is surrounded by base....but....it also says that it could dehydrate spontaneously even without heat.
