Which of the following possesses highest melting point?
Which of the following possesses highest melting point?
Open in App
Solution
The correct option is A p-dichlorobenzene
Molecules with better packing in crystal form have higher melting points. In general, molecules with high symmetry has better packing efficiency in crystal lattice than molecules with
low symmetry. p-dichlorobenzene molecule has symmetrical structure and it can fit well in its crystal lattice. The intermolecular forces of attraction are strong. Hence, it possesses highest melting point among given options.
Hence, option (a) is the correct answer.
