Aldol Condensation

Aldol condensation is a type of organic reaction that involves the condensation of two carbonyl compounds, usually an aldehyde and a ketone, to form a β-hydroxy carbonyl compound, also known as an aldol. The word “aldol” is a combination of “aldehyde” and “alcohol”. The reaction typically requires a base catalyst, such as sodium hydroxide, to…

Oxime

An oxime is a chemical compound that contains a nitrogen atom connected to a carbon atom via a double bond (C=N-OH). Oximes are typically formed by the reaction of aldehydes or ketones with hydroxylamine. They are important intermediates in organic synthesis and are used in a variety of applications, including as reagents in analytical chemistry,…

Nitriles

Aldehydes and ketones are organic compounds that contain a carbonyl group, which is a carbon atom double-bonded to an oxygen atom. In aldehydes, the carbonyl group is at the end of a carbon chain, whereas in ketones, it is in the middle. Nitriles, also known as cyano compounds, are organic compounds that contain a triple…

Ketones from acid chlorides

Ketones can be synthesized from acid chlorides through a reaction called Friedel-Crafts acylation. This reaction involves the reaction of an acid chloride with a Lewis acid catalyst, such as aluminum chloride (AlCl3), to form an acylium ion intermediate. The acylium ion then undergoes a nucleophilic attack by an arene, which leads to the formation of…

C-O bond cleavage reactions

C-O bond cleavage reactions involve breaking the bond between a carbon atom and an oxygen atom in a molecule. These reactions can occur through a variety of mechanisms, including homolytic cleavage, heterolytic cleavage, and acid-catalyzed cleavage. Homolytic cleavage occurs when the bond between carbon and oxygen is broken evenly, with each atom receiving one of…

Preparation by Williamson’s synthesis

Williamson’s synthesis is a method used to prepare ethers. The general reaction involves the reaction of an alkoxide ion with a primary alkyl halide or a primary alcohol with an alkyl halide in the presence of a strong base such as sodium or potassium hydroxide. The reaction mechanism involves the formation of an alkoxide ion…

Carboxylic Acids

Carboxylic acids are organic compounds that contain a carboxyl functional group (-COOH). This functional group consists of a carbonyl group (C=O) and a hydroxyl group (-OH) bonded to the same carbon atom. The general formula for carboxylic acids is R-COOH, where R represents a hydrocarbon chain or a hydrogen atom. Carboxylic acids can be classified…

Thionyl chloride

Thionyl chloride (SOCl2) is a chemical compound that is commonly used as a reagent in organic chemistry for various reactions, such as the conversion of alcohols to alkyl chlorides, carboxylic acids to acid chlorides, and amides to nitriles. Thionyl chloride is a colorless to slightly yellowish liquid with a pungent odor. It is highly reactive…

Reactions with: Sodium

Sodium is a highly reactive alkali metal with the symbol Na and atomic number 11. It has a silvery-white appearance and is soft enough to be cut with a knife. Sodium reacts vigorously with water to produce sodium hydroxide and hydrogen gas. It also reacts with oxygen to form sodium oxide and with halogens to…

Their stereochemical aspects

Stereochemistry is the study of the three-dimensional arrangement of atoms in molecules and the way that these arrangements affect the chemical and physical properties of those molecules. One of the most important concepts in stereochemistry is chirality, which refers to the property of a molecule that cannot be superimposed on its mirror image. Molecules that…
