✓
Answer
Correct option: C.
An elimination reaction
c
(c)Alkyl halide gives alkene on elimination, reaction takes place in presence of alc. $KOH$.
(c)Alkyl halide gives alkene on elimination, reaction takes place in presence of alc. $KOH$.
$C{H_3}C{H_2}Br + Alc\,.\,KOH \to C{H_2} = C{H_2} + KBr + {H_2}O$
There are two types of elimination reactions.
(a) ${E_1} \to $ Unimolecular elimination
(b) ${E_2} \to $ Bimolecular elimination
