What Is Another Name For A Condensation Reaction
What Is Another Name For A Condensation Reaction? It is also known as dehydration synthesis reaction. Condensation reaction is such a reaction which involve combination of two molecules in presence of catalyst releasing water and other molecule as by product. Dehydration is another name of condensation reaction as name suggests that it release small molecule of water. Condensation reaction play vital role in the formation of polymers i.e nylon, polyester and epoxies.
Types Of Condensation:
Condensation reaction follow a specific mechanism in order to give rise to the required products. Reactants combine to form product releasing water. There are different types of condensation. Types of condensation, may vary due the mechanism of reaction, different types reactants and as well as the products formed also determine the type of reaction.
What Is Condensation:
In condensation, two molecules combine in presence of catalysts to form product ,releasing a small molecule. The small molecule can be water or any other molecules including chloride, methanol, acetic acid.
Daily Life Processes:
In our daily life we observe the phenomena of rain fall. Water vapors in the atmosphere condense to form liquid droplets. Which is observed as rain. Condensation reaction had a wide range of application including amino acids formation, in lubricant industry and many more.
Intramolecular Condensation:
Intramolecular condensation is the interaction between atoms of same molecule. Such molecules which contains two carbonyl functional groups can easily form a ring through intramolecular adol reaction. As this reaction is within same molecule, so the enolate donor and acceptor are on same molecule making the reaction more feasible and easy. Such molecules are[dialdehyde, keto aldehydes.
Intermolecular:
In intermolecular condensation as name suggests, this type of condensation occurs between two separate molecules. So the acceptor and donor molecules are far from each other thus reducing rate of reaction. As in intramolecular condensation, the distance between the donor and acceptor molecule is less thus the rate of reaction is much faster as compared to intermolecular condensation.
Esterification:
It is a type of condensation reaction , which forms esters from alcohol and carboxylic acid. An organic acid and alcohol combine to form ester and also release water. In presence of sulphuric acid ester is formed, which of sweet taste. Simply the chemical reaction followed to form ester is called esterification. Five steps are involved in the formation of ester which are as follow:
- Cation Formation
- Carbon Delocalization
- Proton Transfer
- Pi Bond Formation
- Formation Of Ester
Methods Of Esterification:
Esters can be formed in three ways. They can be formed by combination of acid anhydride and alcohol, by combination of acid chloride and alcohol and also from carboxylic acid and alcohol.
1. Acid Anhydride And Alcohol:
This reaction is slower as compared to acid chloride. To obtain esters, there is need to warm the mixture.
2. Acid Chloride And Alcohol:
You can also make ester using acid chloride with alcohol at room temperature . You will get good quality of ester, as acid is used in form of steam. Such as combination of benzoyl chloride and alcohol to form ester.
3. Carboxylic Acid And Alcohol:
For the formation of ester by combination of carboxylic acid and alcohol , heat them in presence of sulphuric acid, which act as catalyst to speed up the reaction. You may use ethanoic acid in combination with propanol.
Properties Of Esters:
Esters are named according to the name of carboxylic acid participating in the esterification.
Esters have sweet taste and pleasant smell, therefore widely used in the perfume and food industries. Esters being organic in nature are part of oils and fats which we use in our daily.
Saponification:
It is hydrolysis of an ester, in presence of sodium hydroxide which give alcohol and sodium acid. Soap is the result of saponification, which we are using in our daily life for cleansing purpose. Soaps are long chain of fatty acids which are sodium or potassium salt. In saponification reaction base reacts with fats to form glycerol and soap molecules. Saponification is extensively used to create hard and softs soaps. It is also recommended to use saponification for fire extinguishing.
Polymerization:
It is the process in which small molecules combine to form large molecules called polymers. Polymer is a long molecule consists of similar building blocks which are linked each other through covalent bond. The small molecules which are arranged in specific way to form polymers are called [monomers.
Monomers:
So , monomers are the building block of of polymers. In short, Polymerization frame small molecules in form of polymers which are of various shapes and sizes. There are two types of polymerization:
1. Condensation Polymerization:
In condensation polymerization, water molecule is lost as result of combination of monomers by covalent bond. When covalent bond is formed between monomers, each monomer give part of water molecule. one monomer provide hydroxyl group (OH) and other molecule give hydrogen atom. For breakdown of polymers into monomers hydrolysis is done which reverse the condensation process.
Synthesis:
There is wide range of application in our daily life which are as result of polymerization. All proteins, DNA, RNA , disaccharides, polysaccharides are bio polymers, found in our body naturally. Some synthetic polymers are of great importance.
2. Adol Condensation:
It is a condensation reaction in which, enol reacts with the carbonyl compound to form hydroxy aldehyde. As result of adol condensation, a carbon to carbon bond is formed, thus are good bond forming reactions. This reaction is mostly discussed in organic chemistry as well as in biochemistry. The Ist step of this reaction is adol reaction next followed by dehydration, which is removal of water.
Dehydration Reaction:
It can be alternate name for condensation reaction. Dehydration mean removal of water. In this reaction water molecule is removed from reactant. One reactant is involved in process of dehydration. These reactions mostly occur in organic chemistry.
Examples:
Examples include in dehydration reaction are conversion of alcohol to alkene, dehydration of ethanol to ethylene. In addition, many metal salts are present in form of hydrates having water molecules in their structure.
Summary:
Condensation reactions are part of our daily life. They are occurring in our body as well as in our surrounding. Condensation reaction involves removal of water molecule , as result of combination of two or more reactants in presence of any catalysts. This reaction is usually confused with dehydration reaction. In dehydration reaction water is released from single reactant molecule while in condensation two reactant molecules are involved. There are different types of condensation which are utilized for multiple purpose to obtain required products.
Uses:

Formation Of Clouds:
Clouds are formed as result of condensation. when water vapors in atmosphere combine with the cold air forming clouds. Later on, these clouds help in rainfall.
Dew And Humidity:
Humidity is the measure of water vapors in air. When the temperature of the air decrease to dew point, water condenses on the earth as dew or fog. If temperature get even lower the dews start freezing.
