Comprehension
`E_2` raction `rarr` Elimination bimolecular
In the general mechanism of the `E_2` reaction a strong base abstract a proton on a carbon atom adjacent to the one of the leaving group. As the abstracts a proton , a double bond forms and the leaving group leaves.
In given pairs, which compound is more reactive toward `E_2` reaction

`(Q) CH_3 - underset((III))underset(Br) underset(|)CH-CH_3 " "CH_3 - underset((IV))underset(Br)underset(|)CH - CD_3`
