Question

Carefully evaluate the four pure structural isomers of bromobutane ($C_4H_9Br$). Which specific highly distinct isomer intrinsically strictly natively physically boils at the lowest possible temperature?

Prashant Kotian · Accepted Answer

Correct answer: D. Extensive hydrocarbon branching structurally forces the molecule into a highly compact, increasingly spherical shape. This drastically minimizes the macroscopic surface area, thereby severely massively weakening the intermolecular London dispersion forces and severely lowering the boiling point.
