ANSWER

what is aryl halide, benzene, haloarene

Posted by Irfan Ahmed 4 years, 2 months ago

CBSE > Class 12 > Chemistry

1 answers

Sia ? 4 years, 2 months ago

halide - an aryl halide is an aromatic compound in which one or more hydrogen atoms, directly bonded to an aromatic ring are replaced by a halide. The haloarene are different from haloalkanes because they exhibit many differences in methods of preparation and properties.
benzene - Benzene is an organic chemical compound with the molecular formula C₆H₆. The benzene molecule is composed of six carbon atoms joined in a planar ring with one hydrogen atom attached to each. Because it contains only carbon and hydrogen atoms, benzene is classed as a hydrocarbon.
haloarene - In organic chemistry, an aryl halide (also known as haloarene) is an aromatic compound in which one or more hydrogen atoms, directly bonded to an aromatic ring are replaced by a halide.

The tendency to show 2 oxidation state diminishes from sulphur to polonium

Posted by Ramandeep Kaur Bhatti 4 years, 3 months ago

Preeti Dabral 4 years, 3 months ago

As the atomic size increases, electronegativity decreases, hence tendency to show negative oxidation also decreases. Therefore tendency to show -2 oxidation state decreases down the group.
