When heated with strong bases, alkyl halides typically undergo a 1,2-elimination reactions to generate alkenes. Typical bases are

N a O H

or

K O H

or

N a OR

or

K OR

(alkoxide) especially

N a OEt

or

K OtB u

in the alcohol as solvent.

3^{o}

halide easily give elimination reaction. alcoholic

K O H

favours

E_{2}

reaction order

3^{\circ} > 2^{\circ} > 1^{\circ}
