NITROGEN
Nitrogen is the great strength of the triple bond makes N2 thermodynamically and kinetically stable but moderately electronegative element. The atom can form three single bonds, usually with a pyramidal geometry, but also has a notable tendency to multiple bonding. It's usually not rich redox chemistry is illustrated in the Frost diagram.
Dinitrogen builds up 79 mol % of dry air. The element is essential for life and is one of the elements often in short produce, as fixation of atmospheric nitrogen to form chemically usable compounds is a difficult process.
Nitrogen is finding from the atmosphere by fractional distillation and liquefaction. Its normal boiling point (-196°C or 77 K) and its ready availability build it a useful coolant. It collides directly with rather few elements and is often need as an inert filling or 'blanket' for metallurgical processes. The majority of industrial nitrogen is used to build ammonia and further compounds.

Q. What is Peroxodisulphuric Acid? It is also known as perdisulphuric acid or simply persulphuric acid. The acid can be obtained by the action of chlorosulphonic acid on H 2 0

Q. Show the Basic Definitions of coordination compounds? Some of the terms which we use in connection with coordination compounds carry specific meaning and thus form a kind of
Q. Illustrate the structure of Alkanes? Ans. Alkanes have the general formula C n H 2n+2 . This means that for every n atoms of carbon, there are 2n + 2 atoms of hydrogen.
Reaction of ammonia with diborane at 475K gives a compound B3N3H6 known as borazine or borazole: Borazine is best prepared by reducing B-trichloroborazme with sodium borohy
