(i) Physical state: Haloarenes are colourless liquid or crystalline solid.
(ii) Solubility: They are insoluble in water, but dissolve readily in organic solvents. Insolubility is due to inability to form hydrogen bonding in water. Para isomer is less soluble than ortho isomer.
(iii) Halo-arenes are heavier than water.
(iv) B.P. of halo-arenes follow the trend. Iodo arene > Bromo arene > Chloro arene.
