What is the purpose of refluxing? Which reaction conditions are indicated with reflux? Will you apply heat? How do you know the temperature at which you should reflux?

I think it is "A reflux system is used to condense vapours escaping from the hot flask. "

Please help.



Your definition is ok but it doesn't go quite far enough. The vapors are condensed BUT the condenser is mounted in such a way (usually vertically on top of the boiling flask)that the condensed vapors return to the boiling pot to be reboiled. The other parts of the question are specific to a reaction and don't have general answers. I hope this helps.
