Vedclass · Answer

(C) An $E_2$ reaction requires the presence of at least one $\beta$-hydrogen atom relative to the carbon atom attached to the halogen ($\alpha$-carbon).In the structure shown in option $C$ ($1$-bromo-$2,2$-dimethylbutane),the $\alpha$-carbon is attached to a quaternary carbon (a carbon with no hydrogen atoms). Since there are no $\beta$-hydrogens available on the adjacent carbon,this molecule cannot undergo an $E_2$ elimination reaction.
