Quantum Numbers
Orbitals of electrons in atoms differ in size shape and orientation. Definite energies and angular movements characterize atomic orbitals. The state of an electron in any atom is defined by certain permissible values of energy and angular momentum, which describe its location with respect to its nu..
..Mechanism of Racemisation
Mechanism of Racemisation - A compound where the chiral carbon atom is attached to a hydrogen atom and an electron-attracting group can undergo racemisation readily. The mechanism is enolisation. For e.g..

Mechanism of Reaction - A balanced chemical equation represents the overall result of a chemical reaction. However, at the molecular level, more than one reaction step might be involved. Most reactions can be broken down into a sequence of elementary reactions. This breaking down of a rea..

Mechanical separation
When the (+) and (-) isomers or their salts form well defined crystals showing hemihedral faces, hand picking is used to separate them. Pasteur separated sodium ammonium racemate crystals by mechanical separation in 1848. Below a certain temperature the enantiomorphs crystallize separate..
Mechanism of Electrolysis
The process of electrolysis is exactly opposite to one that takes place in a voltaic cell. A voltaic cell or a battery uses its chemical energy to produce electrical energy. While in electrolysis, electrical energy is used to bring about a chemical change. Humphrey Davy (1807) showed this in his ex..
Azimuthal quantum number or angular quantum number
The Azimuthal quantum number determines the angular momentum of the electron, denoted by the letter 'l'. The value of 'l' gives the sub level or sub shell in a given principal energy shell to which the electron belongs. It can have only positive integral values from zero to (n-1) where '..
Magnetic Quantum Number (m)
This quantum number describes the behavior of the electrons in the magnetic field. We know that the movement of electrical charge is always associated with magnetic fiel..

Tutor has given me a lot of good advise for my study. They has the package to be the best and the best teachers! they are not just have the teaching skills and understanding the subject matters as well. Thank you.
Turtors are so good, and patient and most important knows their stuff. They really tutor in a very professional way. Their system is unique and they really knows how to explain and made sure you undertand. They even put stuff from a book into the white board, just to show me how the process of my question - Paul
It has tought me how to make my word more explained and This has tought me alot that i need to know , I am thankful -- Mark
I have a personalized assistance with an expert math tutor at my home itself, It's wonderful - Shijo
