Question

Explain an additional reaction with an example?

Answer 1

Hint: We need to know that during a chemical substance it transforms chemically into other chemical substances. And the species formed during the chemical reaction is known as a product. The reactant converts into products by passing them to a high energy transition state. And the chemical reactions are divided into different types, that is, synthesis, decomposition, addition, single replacement reaction and double replacement reaction.

Complete answer:
In the case of an addition reaction, the unsaturated hydrocarbon is reacted with another substance and there is a formation of a single product and the reaction is known as addition reaction. Consider an example, when the ethene is reacting with hydrogen in the presence of heat and nickel catalyst and there is a formation of ethane. Let’s see the reaction,
${H_2}C = C{H_2} + {H_2}\xrightarrow[{Heat}]{{Ni}}{H_3}C - C{H_3}$
The addition reaction is mainly divided into two types and that is, electrophilic addition reaction and nucleophilic addition reaction. In the case of electrophilic addition reaction, it is an addition reaction, with a chemical compound containing a triple bond or a double bond having the broken pi bond and there is a formation of a new sigma bond.

Note:
In the case of a chemical reaction, one or more chemicals are transformed into one or more other chemicals by occurring any of the chemical reactions like synthesis, decomposition, single replacement reaction and double replacement reaction. First we have to analyze the given reactant and the product and place it in any one of the categories of chemical reactions and find the product accordingly.
