Question

What is an additional reaction?

Answer 1

Hint : A chemical reaction is a mechanism in which one set of chemical substances is chemically transformed into another set of chemical substances. It includes only changes in electron positions in the formation and breaking of chemical bonds between atoms, with no change in the elements present.

Complete Step By Step Answer:
In organic chemistry, an addition reaction is an organic reaction in which two or more molecules combine to create a larger one. Unsaturated organic compounds, such as alkenes with a carbon-to-carbon double bond and alkynes with a carbon-to-carbon triple bond, as well as aldehydes and ketones with a carbon-to-oxygen double bond, undergo additional reactions.
An additional reaction is a mechanism in which double or triple bonds are broken completely or partially in order to accept more atoms or groups of atoms in a molecule. Since the reaction allows the carbon atoms to become saturated with the maximum number of attached groups, addition reactions to alkenes and alkynes are often referred to as saturation reactions.
In general, electron-seeking or electrophilic reagents are said to initiate the addition of alkenes, while electron-rich or nucleophilic reagents are said to initiate the addition of alkynes, aldehydes, and ketones. Other types of addition reactions include catalysed addition reactions, such as the self-addition of alkenes which catalysed by acids or the hydrogenation of alkenes, aldehydes, and ketones which catalysed by metals; cyclic compound formation; and chain mechanism addition reactions.
As a result, we can deduce that an addition reaction is any of a group of chemical reactions in which an atom or group of atoms is added to a molecule.

Note :
It's important to remember that only chemical compounds with multiple bond characters will undergo an addition reaction because a double or triple bond is normally broken to form the necessary single bonds. A single product is formed when an unsaturated hydrocarbon interacts with another material.
