Statement 1
Boiling point of n-pentane is higher than that of neopentane while the melting
point of \(n\) -pentane is lower than that of neopentane.
and
Statement 2
Boiling point of alkanes depend upon the surface area while melting point
depends upon the packing of molecules in the solid state. Neopentane fits into
the crystal lattice more readily and it has minimum surface area compared to
n-pentane.
