Elimination reactions
When a haloalkane with b-hydrogen atom is heated with alcoholic
solution of potassium hydroxide, there is elimination of hydrogen
atom from b-carbon and a halogen atom from the a-carbon atom Location of aaaaa and
bbbbb carbon in a
molecule
Carbon on which
halogen atom is
directly attached is
called a-carbon and
the carbon atom
adjacent to this
carbon is called
b-carbon Rationalised 2023-24

Chemistry
As a result, an alkene is formed as a product Since b-hydrogen
atom is involved in elimination, it is often called bbbbb-elimination
