Quick and easy way to learn the organic nomenclature (with video).

Most of the students find it difficult to learn and apply the knowledge related to the organic nomenclature. Here in this post you simply need to memorise the following table and after that there are a few steps related to that.

What is the mechanism for anti markovnikov addition or kharasch effect or peroxide effect ?

The mechanism for this kind of reaction involves the formation of free radicals, and the relative stability of different molecules will decide the formation of major and minor products. Step 1 , Chain initiation :- First of all , the homolytic cleavage takes place in peroxide molecule as shown below :- Step2 Chain propagation :-

Why the but-2-ene is major product of beta elimination of 2-Bromobutane ?

This is due to the following reason :- This is in accordance with sytzeff rule that whenever two alkenes are theoretically possible during a dehydrohalogenation reaction , it is always the more highly substituted alkene which predominates . It can also be best understood by the following illustrations showing the stabilizes of primary(1°) , secondary

How the addition of hydrogen halide takes place in case of unsymmetrical alkenes ?

In case of unsymmetrical alkenes the addition of hydrogen halide takes place according to the markovnikov’s rule . During this reaction under markovnikov’s rule the positive part of the attacking reagent joins with the carbon with more number of Hydrogen and the negative part of attacking reagent joins with the more substituted carbon.

How we can prepare dibromoethane from ethene ?

We can make the dibromoethane from ethene by the addition of halogen in ethene , in the presence of carbon tetrachloride. In the presence of ether as a solvent the above reaction takes place. The dihalo products are formed in which the halogen groups are present on adjacent carbon atoms.
