Question

Explain following reaction with example : (a) hydrogenation reaction .
(b) oxidation reaction .
(c) substitution reaction .
(d) saphonification reaction .
(e) combustion reaction .

Answer 1

I think it's saphonification reaction

Answer 2

Soaps are sodium or potassium salts of long chain fatty acids. When triglycerides in fat/oil react with aqueous NaOH or KOH, they are converted into soap and glycerol. This is called alkaline hydrolysis of esters. Since this reaction leads to the formation of soap, it is called the Saponification process

An oxidation-reduction (redox) reaction is a type of chemical reaction that involves a transfer of electrons between two species. An oxidation-reduction reaction is any chemical reaction in which the oxidation number of a molecule, atom, or ion changes by gaining or losing an electron.

Substitution reaction (also known as single displacement reaction or single substitution reaction) is a chemical reaction during which one functional group in a chemical compound is replaced by another functional group. Substitution reactions are of prime importance in organic chemistry.


A combustion reaction is a type of chemical reaction where a compoundand an oxidant is reacted to produce heatand a new product. The general form of a combustion reaction is the reaction between a hydrocarbon and oxygen to yield carbon dioxide and water:

hydrocarbon + O2 → CO2 + H2O

In addition to heat, it's also common (although not necessary) for a combustion reaction to release light and produce a flame
