Vedclass · Answer

(C) The boiling point of an alkane depends on the surface area and the strength of the van der Waals forces.As the number of carbon atoms increases,the molecular weight and surface area increase,leading to stronger van der Waals forces and a higher boiling point.$n$-heptane $(C_7H_{16})$ has $7$ carbon atoms,$n$-butane $(C_4H_{10})$ has $4$ carbon atoms,neopentane $(C_5H_{12})$ has $5$ carbon atoms,and isobutane $(C_4H_{10})$ has $4$ carbon atoms.Since $n$-heptane has the longest carbon chain and the highest molecular weight,it exhibits the strongest intermolecular forces.The boiling points are: $n$-heptane $(98.4 \ ^\circ C)$,neopentane $(9.5 \ ^\circ C)$,$n$-butane $(-1 \ ^\circ C)$,and isobutane $(-11.7 \ ^\circ C)$.Therefore,$n$-heptane has the highest boiling point.
