resonating structures of oxides of nitrogen

Oxides of nitrogen provide a fascinating picture from the point of view of their varied structures and diverse chemical behavior. They range from N 2 O (oxidation state of nitrogen +1) through NO, N 2 O 3 , NO..

The dioxides are acidic in nature and acidic character decreases as we move down the group. (iii) All the elements of this group form trioxides of the formulae MO 3 . SO 3 is a gas. It is obtained by catalytic oxidation of sulphur dioxide. In the solid state it exists as a cyclic trimer o..

The phenomenon of resonance was put forward by Heisenberg to explain the properties of certain covalent molecules. Most covalent molecules have a unique Lewis formula (dot structure), which explains the bonding in that molecule. Some molecules lend themselves two or more d..

Oxides - The elements of group 15 combine with oxygen either directly or indirectly to form oxides. The important oxides of group 15 elements along with their oxidation states are listed in table. Thus, it is nitrogen, which forms all oxides..

Structures of Oxides of Iron - Iron forms three different types of oxides, which are FeO, Fe 2 O 3 and Fe 3 O 4 . These are non-stoichiometric (the ratio of cations and anions may vary from that given in the formula) and are easily oxidized or reduc..

Iron forms three different types of oxides, which are FeO, Fe 2 O 3 and Fe 3 O 4 . These are non-stoichiometric (the ratio of cations and anions may vary from that given in the formula) and are easily oxidized or reduced into each other. These aspects can be explained ..

The sources of oxides of nitrogen are mainly emissions from chemical and metal fabrication plants, agricultural fertilizers, automobile emissions, electric power plants and explosion of thermonuclear weapons in the atmosphere. NO molecule also catalytically converts O 3 to O h..
