reaction mechanism of halogenation

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 ..

Ammonia reacts with halogens but the type of halogen and reaction conditions determine the nature of product..

In halogenations, the nature of the products depends upon the reaction conditions. Benzene in the presence of a halogen carrier e.g., FeCl 3 or iodine, reacts with chlorine and bromine even in dark and at room temperature to give mono- and di-halo derivatives, ..

A balanced chemical equation represents the overall result of a chemical reaction. However, at the molecular level, more than one reaction step might be involved. Most reactions can be broken down into a sequence of elementary reactions. This breaking d..

In acetic acid, halogen atoms successively replace the three hydrogen atoms of the alkyl group. ..

Phenyl alkyl ethers undergo usual halogenation in the benzene ring. For e.g., Anisole undergoes bromination with Br 2 in ethanoic acid even in absence of Iron (III) bromide catalyst...

Alkynes react with halogens (Cl 2 or Br 2 ) in the dark, forming dihaloalkenes first and finally tetrahaloalkanes. The reaction gets accelerated in the presence of light or halogen carriers. RCCH RCX=CHX RCX2CX2 alkyne dihal..

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 ..
