1. Rearrangement reaction: In organic chemistry, a rearrangement reaction is a broad class of organic reactions where the carbon skeleton of a molecule is rearranged to give a structural isomer of the original molecule. Often a substituent moves from one atom to another ... (Chemical reaction where a molecule is turned into a structural isomer of itself) [100%] 2023-09-08 [Rearrangement reactions]
