nature of hydrogen halogen bond

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, ..

The sp 2 hybridized carbon atom in the C-X bond in haloarene molecule is more electronegative than the sp 3 hybrid carbon atom in alkyl halide. This carbon has less tendency to release electrons to the chlorine atom and so the C-Cl bond in aryl halides is less polar..

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

B 2 H 6 reacts with halogens under different conditions to form halodiboranes. ..

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

The elements placed in group VIIA of the periodic table are called halogens. All these elements form salts called halides, e.g. NaCl, NaI, KCl, KI etc. Halogen is an ancient Greek word meaning 'salt producer'. Halogens have seven electrons in their valence shell and s..

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. ..
