General Organic Chemistry
Carbon is an necessary element of organic substance; it has four electrons in its outer most shell.
As per to the ground state electronic arrangement of carbon, carbon is divalent. Tetravalency of carbon may be described by promoting one of the 2s2- electrons to the unoccupied 2pz1 atomic orbital.
The four valencies of carbon molecule are similar and they are symmetrically arranged around the carbon molecule. Illustrated by Le Bell and Van't Hoff the four valencies of carbon do not lie in one surface. They are going in the direction of the corners of a regular tetrahedron along with carbon atom at the centre and the angle among any two valencies is 109o28.
why f-block elements are called inner transition elements?
Q. Illustrate Born-Haber cycle? Boron is always covalent and does not form,B 3+ ions, because' the energy required to remove three electrons is very high. Many simple compo

Osmotic pressure: Osmosis process is the movement of a solvent from a solution of lower solute concentration (higher solvent concentration) to one of the higher solute concentr
Q. What do you mean by Fusion Reactors? Ans. It is pretty difficult to achieve fusion in the laboratory. A lot of energy is needed to initiate the fusion process and the
Transition metals are substances of the d block that form compounds where electrons from d orbitals are ionized or otherwise accept in bonding. Typical transition metal charac
Q. Reactions with metals? Ans. Halogens commonly undergo reactions with metals. Halogens react with the alkali metal family, Group IA in the periodic table. For example,
