Explain the difference in the melting point, boiling point, and densities of cycloalkane with those of the corresponding normal alkanes.

Explanation

a. Cycloalknes have higher melting point than normal alkanes with the same number of C atoms because they have more compact shapes than n-alkanes and are packed more closely in the crystal lattice or solid state. They behave like compact branched-chain alkanes.
b. Cycloalknes have lower boiling point than normal alkanes with the same number of C atoms because they are more compact or have lesser surface area and, thus, have weaker intermolecular van der Waals forces of attraction.
c. Densities of cycloalknes are more than normal alknes with the same number of C atoms because they can be closely packed in teh liquid state also.
