Amines Amines are the organic compounds derived from ammonia (NH3) by replacing its one or more hydrogen atoms by alkyl or aryl group. For example: Structure of...

Physical Properties of ethers: Miscibility: Miscibility of ethers with water resembles those of alcohols of the same molecular mass. This is due to the fact that...

Ethers Ethers are classified as simple or symmetrical, if the alkyl or aryl groups attached to the oxygen atom are the same, and mixed or...

Physical properties of Phenols Phenols are colourless liquids or crystalline solids but become coloured due to slow oxidation with air. ...

General methods of preparation of phenols are described below: Preparation of phenol From benzene sulphonic acid: Preparation of phenol From haloarenes: Preparation of phenol From diazonium salt: Commercial...

Structure of phenol In phenols, the –OH group is attached to sp2 hybridised carbon of an aromatic ring. The C–O bond length (136 pm) in...

Common naming system: The simplest hydroxy derivative of benzene is a phenol. Phenol is the common name as well as an...

Phenols Phenols are the compounds formed when a hydrogen atom in an aromatic ring, is replaced by a hydroxyl group (-OH group). For example: Classification Of...

Two commercially important alcohols are methanol and ethanol. Methanol, CH3OH Preparation of Methanol: Methanol is mainly produced by catalytic hydrogenation of carbon monoxide at high pressure and...

Physical properties of alcohols Lower alcohols are liquid at room temperature while higher ones are solid. The boiling...
