Q. An alkane with a molecular formula $C _{6} H _{14}$ reacts with chlorine in the presence of light and heat to give two constitutionally isomeric monochlorides of molecular formula $C _{6} H _{13} Cl$. What is the most reasonable starting alkane?

Solution:

$2,3$-dimethylbutane has $12$ equivalent $1^{\circ}H$ and two equivalent $ 3^{\circ}$ hence it gives two constitutionally isomeric monochlorides of molecular formulae
