MnO2 oxidation reaction with example

 

MnO2 oxidation introduction 

MnO2 oxidation reaction is essential both in organic as well as in inorganic chemistry. MnO2 oxidation process is especially used for organic synthesis.

MnO2 is an inorganic chemical compound. It is also known as manganese (IV) oxide.

 

What are synthesis reactions in organic chemistry?

In chemistry, synthesis reaction is very important chemical reaction. The synthesis reaction occurs mainly in the synthetic synthesis of various organic compounds.

The synthesis reaction occurs in several stages. The synthesis reaction involves the addition of reactants to produce products.

The organo chemical reactions in which one or more reactants are artificially added to produce products through several steps is called a synthesis reaction.

An important example of organic synthesis reaction is mescaline from 3, 4, 5-trimethoxy benzoic acid.

 

What is dehydration synthesis reaction in organic chemistry?

 

The dehydration synthesis reaction is an important reaction in organic chemistry. This is because compounds like alkene, aldehyde, cyanide, ether, ester etc. are synthesized by this reaction.

The dehydration synthesis reaction is the reverse of the hydration reaction. In the process of dehydration synthesis, water molecules are removed from the reactant and produce products.

 

Why Ni⁺² paramagnetic whereas Zn⁺² diamagnetic?

 

Para magnetism and diamagnetism of a substance depends on the number of electrons occupied by it. A paramagnetic substance is one that contains one or more unpaired electrons.

On the other hand, a diamagnetism substance is one that does not contain any odd electrons. Now, Ni ⁺² ion is 3d⁸ system. According to Hund’s rule the outer electronic configuration of Ni⁺² ions is [Ar] 3d⁸. 

From electronic configuration of Ni ⁺² ion, it has been found that it has two unpaired electrons.

Now, depending upon the hybridization, there are two types of possible structure of Ni ⁺² ion are formed with co-ordination number 4.

If the complex involves ‘sp3’ hybridization, it would have tetrahedral structure. Again, if the complex involves ‘dsp2’ hybridization, it would have squareplanar structure.

 

What is dehydrogenation of alcohol reactions in organic chemistry?

 

Dehydrogenation is an important chemical reaction, usually associated with the removal of hydrogen from organic molecules. It is the opposite reaction of hydrogenation.

Dehydrogenation reactions produce aldehydes, ketones, alkenes, alkynes, polymers and aromaticand aliphatic closed chain compounds.
