Vedclass · Answer

(B) The reaction starts with $2$-chloro-$3$-methylbutane. Treatment with $EtONa$ (a strong base) and heat leads to an $E2$ elimination reaction. The major product formed is the more substituted alkene,which is $2$-methylbut-$2$-ene (Saytzeff product). Subsequent addition of $HBr$ to $2$-methylbut-$2$-ene follows Markovnikov's rule,where the $H^+$ adds to the carbon with more hydrogens and the $Br^-$ adds to the more substituted carbon. This results in the formation of $2$-bromo-$2$-methylbutane as the major product '$Y$'.

The major product '$Y$' in the following reaction is
