Melting points, the melting points of alkanes do not show a very smooth gradation with the increase in molecular mass. Hydro- C3H8 C4H10 C5HI2 C6H14 C7H16 C8H18 carbon, melting. This is due to the fact that branching of the chain makes the molecule more compact and brings it closer to a sphere. Due to the weak interparticle forces, the first four members (C1 to C,J are gases; the next thirteen members, (C5 to C17) are liquids while the higher members are waxy solids. Boiling points, alkanes generally have low boiling points.

Consequently, boiling point also increases. However, they are soluble in non-polar solvents like ether, carbon tetrachloride, etc. The molecule which fit into crystal lattice more easily due to their symmetrical structures summary essay about grafitti usually have high lattice energy and therefore, high melting points. This decreases the surface area and hence, the magnitude of interparticle London dispersion force and leads to the decrease in boiling point.
