Chemistry students watching their reaction progress like: ๐ โ ๐ โ ๐ โ ๐ โ ๐
Nothing captures the emotional rollercoaster of organic synthesis quite like the Pentaerythritol formation. You start all confident with your simple aldehydes, thinking "I got this!" Then suddenly your third aldol condensation hits and things get... concerning. By the time the Cannizzaro reaction finishes, your hopes, dreams, and apparently your face have completely decomposed.
This is basically what happens when you tell your professor "my synthesis should be done by Friday" and the chemistry gods hear you.
