"WebE1 reaction is a type of elimination reaction in organic compounds. A beta-hydrogen and a leaving group attached to two adjacent carbon atoms are removed from a compound (substrate) to form a double bond. The removal usually takes place in two steps in the presence of a Lewis base or acid, resulting in an alkene. " - Reaction elimination e1
