benzene ring oh

After taking into account account the above observed facts, Kekule (1865) suggested a ring structure for benzene. According to him, six carbon atoms occupied six corners of a regular hexagon in benzene and each carbon carried one hydrogen atom. To satisfy the tetraval..

. Hence sideways overlapping of '2p' orbitals of carbon atoms can form two sets of p -bonds as show..

Halogenation of arenes is an electrophilic substitution reaction. The function of the halogen carrier is to generate 'electrophile' which attacks the benzene ring to form the product. With excess halogen, the second halogen also gets introduced in the ring at ortho and..

Primary and secondary amines combine with benzene sulphonyl chloride (C 6 H 5 SO 2 Cl) to form sulphonamides. The product formed by the action of secondary amine on benzene sulphonyl chloride does not dissolve in an alkali. This is because there is no hydrogen atom attached to t..

Aromatic compounds are those carbocyclic compounds that contain at least one benzene ring. The ring of six carbons in benzene or any of its derivatives is termed benzene ring or nucleus. A benzene ring may be represente..

. The simple ether ethoxyethane has been used as an anaesthetic for a long time and is widely used as a solvent too. Some alcohols, phenols and ethers occur in nature and are used in the manufacture of perfumes and flavors due to their pleasant odors. From alcohols various other classes of organic ..

Aromatic Nitro Compounds - Aromatic compounds can be directly nitrated using a mixture of concentrated nitric acid and sulphuric acid. This reaction is an example of electrophilic substitution of benzene. The electrophile is a nitroni..

Halogenation - On treating phenol with bromine, different reaction products are formed. When the reaction is carried out in a solvent of low polarity such as CHCl 3 or CS 2 and at low temperature, monobromo phenols are formed. The highly activating effect of -OH group on the benzeneh..

Electrophlic Aromatic Substitution - The -OH group attached to the benzene ring in phenol activates, it towards electrophilic substitution. It directs the incoming group to ortho and para positions in the ring as these positions become electron rich due to el..
