SN1 mechanism

This mechanism is seen in Nucleophillic Substitution reactions, especially in those compounds in which the Carbon atom is more substituted . The rate of this mechanism depends on the step 1 where the leaving group leave with electron pair and leaves behind a carbocation. The whole rate depends only on one molecule. That’s why itContinue reading “SN1 mechanism”

The SN2 mechanism

This is a type of reaction mechanism that is seen in case of nucleophillic substitution reactions. It is BIMOLECULAR NUCLEOPHILLIC SUBSTITUTION mechanism. In this kind of mechanism two molecules decide the rate of reaction, so it is BIMOLECULAR mechanism. The whole mechanism proceeds through a single step. That concerted step involves the bond breaking andContinue reading “The SN2 mechanism”

What are fuel cells?

This is a very new concept in the field of energy . The conventional energy generators were having a maximum efficiency of approximately 52%. Which is very low . Most of the energy in that system was dissipated in the form of heat lost to the surroundings and in overcoming the frictional forces of theContinue reading “What are fuel cells?”

How the age of mummies , dead bodies and fossils is calculated?

The aging of different organisms is mainly calculated by the special technique called the Radiocarbon dating. In this technique the age of any specimen is calculated on the basis of the present amount of an isotope of a particular element. Isotopes are the atoms of an element that have same atomic number but different atomicContinue reading “How the age of mummies , dead bodies and fossils is calculated?”
