Chlorobenzene (an haloarene) is hydrolysed by treating it with 10% NaOH at 623 K and 320 atmospheric pressure in presence of Cu catalyst. Phenol is obtained by acidification of sodium phenoxide...

Chemical Properties of Haloarenes - Haloarenes are chemically less reactive than haloalkanes. They can undergo the following reactio..

The haloalkanes and haloarenes can be distinguished by the following test..

Polyhalogen derivatives of alkanes are the halogen derivatives of alkanes containing more than one halogen atom per molecule. For example, ethylene dichloride, ethylidene chloride, chloroform, iodoform, carbon tetrachloride, e..

Direct chlorination or bromination of benzene or other aromatic hydrocarbon gives chloroarenes and bromoarenes. These reactions are carried out in the presence of Lewis acids such as ferric or aluminium halides (FeCl 3 , FeBr 3 , AlCl 3 ) in the dark, at ordinary temperatures (310-320 K..

Polyhalogen derivatives of alkanes are the halogen derivatives of alkanes containing more than one halogen atom per molecule. For example, ethylene dichloride, ethylidene chloride, chloroform, iodoform, carbon tetrachloride, et..

Haloarenes are colorless liquids or crystalline solids. Aryl halides are heavier than water. Being heavier than water, they are insoluble in water but soluble in organic solvents. The melting and boiling points of aryl halides are nearly the same as those of alkyl halides conta..

The halogen atom in haloalkane is very reactive and can be easily replaced by nucleophiles whereas the halogen atom in haloarenes is strongly held to the nucleus and cannot be replaced easily with nucleophiles. The differences between haloalkanes and haloarenes are due to the fo..

Haloarenes react with halogens in the presence of ferric salt as catalyst to give ortho para isomers...
