Dear Aksa, Those elimination reactions in which an atom (or a group) is removed from an alpha carbon atom and one from a beta carbon atom (i.e. adjacent carbon atoms) are termed as alpha-beta elimination reactions. Let us consider an example of 1-Bromobutane. When 1- Bromobutane is treated with alcoholic sodium hydroxide, it loses the Bromine atom (Br) and one hydrogen atom from the ?- carbon atom, forming Propene (CH3-CH2-CH=CH2).
