Among the following four aromatic compounds, which one will have the lowest melting point?
1
2
3
4
Explanation:
(B): Out of four aromatic compound only (b) have lower melting point because melting point depends on size and attraction force. Hence, the melting point is lowest for naphthalene 80°C because Naphthalene has low size and lower molecular mass. Melting point \(\simeq 80^{\circ} \mathrm{C}\)
