PCC will give you acetaldehyde OH- rips off an alpha hydrogen, now that attacks carbonyl of another acetaldehyde. This results in hydroxy group on beta position Heat removes or "eliminates" the hydroxy group as water to form a double bond. hope this helped. I wish I could draw this lol. Upvote 0 Downvote
