Base

-
Base - it is any compound which gives OH- ions in the solutions.
Base can be further classified as
1) weak base
2) strong base
3) organic base
4) inorganic base.

1) weak base :- A base which does not dissociates completely in the solution is known as weak base.
e.g. NH3

2) Strong base :- A base which dissociates completely in the solution is known as strong base.
e.g. NaOH

3) organic base:- an organic compound which acts as a base is known as organic base.
e.g. pyridine, methylamine.

4) inorganic base:- an inorganic compounds which has ability to neutralize the orgaic compound & produce salt.

e.g. calcium carbonate.

Hydrogen.

-
Hydrogen,most abundant element in the universe and the third most abundant on the surface of the globe,is being visualised as the major future source of ENERGY. Position of hydrogen in the periodic table: Hydrogen is  first element in the periodic table. It has electronic configuration 1S1. its electronic configuration is similar to the outer electron electronic configuration of alkali metals (ns1). Hydrogen forms oxide , halides  and sulphides It has very high ionization enthalpy. Mostly hydrogen exist as a dihydrogen in the universe . Dihydrogen H2: dihydrogen is the most abundant element in the universe (70% the total mass of the universe) . Isotopes of Hydrogen : Hydrogen has three isotopes :  1.protium 1H1 in this neutron is absent.  2. Deuterium, 2H1 or D 3. Tritium, 3H1.  0r T . These isotopes different form oneanother in respect of their presence of neutrons. Out of these Tritium shows radioactivity. Which emits low energy beta particles . Nat

Reactive intermediates

-
Definition: The branch of chemistry which deals with study of carbon & carbon related compounds is known as organic chemistry. When reactant gets converted into product between that the reactive intermediate are formed. 1) carbonations : The spaces carrying positive charge on carbon atom and having only 6 electrons in its outer valence shell are known as carbonations. 2) carbanions :- the species carrying negative charge on carbon atom and having 8 electrons in its outer valency are known as carbanions 3) free radicals :- an atom having odd number of electrons is known as free radicals. 4) carbens :-   carbens are neutral, divalent carbon intermediates in which carbon is covalently bonded  to two atoms and has two non bonding orbitals containing two electrons between them . this are  electron deficient species. 5) Arynes or Benzynes :  it is a neutral highly reactive intermediate in which the aromatic character has not been much more and disturbed. 6) Nitrenes : Nitr
