What is aldol condensation reaction with example?
undergo aldol reactions (also called aldol condensation) by the use of certain techniques. The reaction is often used to close rings, in which case one carbon provides the carbonyl group and another provides the carbon with an α-hydrogen. An example is the synthesis of 2-cyclohexenone.
What is aldol condensation used for?
It works as an intermediate for the production of perfumes. It is also used in the manufacture of pharmaceuticals, such as a, b unsaturated ketones and the aromatic ketones known as chalcones. It is also generally used to create plasticizers. Aldol Condensation is a classic reaction.
What is formed in aldol condensation?
The product formed in aldol condensation is beta hydroxy aldehyde or beta hydroxy ketone.
What is decarboxylation give example?
Explanation: We get an alkane when we decarboxylate the sodium salt of a carboxylic acid by heating it with soda lime (a 3:1 mixture of caustic soda NaOH and quicklime CaO ). The conversion of isocitrate to α-ketoglutarate is a crucial decarboxylation step in the Krebs cycle for the conversion of glucose to CO2 .
What show is aldol condensation in?
NaOH forms aldol. Reason (R) : Aldehydes and ketones having α-hydrogen undergo aldol condensation.
What are aromatic ketones 12?
Aromatic ketones are important organic intermedi- ates in the industries of flavors, perfumes, pharmaceuticals, and agrochemicals. Traditionally, these ketones were pro- duced by Friedel-Crafts acylation of aromatic compounds using Lewis acids or strong protonic acids as catalysts.
What does a condensation reaction typically produces?
Condensation reaction. A condensation reaction is a class of an organic addition reaction that proceeds in a step-wise fashion to produce the addition product, usually in equilibrium, and a water molecule (hence named condensation). The reaction may otherwise involve the formation of ammonia, ethanol, or acetic acid.
How does a condensation reaction get its name?
The other name for a condensation reaction would be dehydration reaction. This reaction happens when two molecules or compounds react forming a larger molecule and a small H2O molecule. From the name itself, water should be produced.
What is an example of condensation reaction?
Condensation reactions occur mainly in organic chemistry. An example is the reaction between a ketone and hydroxylamine to produce an oxime and water. A similar process involving monomers (polymer building blocks) can be used to produce a polymer in a type of reaction called condensation polymerization.
What is the by product of condensation reaction?
When we talk about condensation polymerization, it is a form of a step-growth polymerization where smaller molecules or monomers react with each other to form larger structural units (usually polymers) while releasing by products such as water or methanol molecule . The by products are normally referred to as condensate .
