Chemical reaction of Carbonyl compounds Definition Chemical reaction of Carbonyl compounds refers to the set of organic reactions involving the nucleophilic addition or substitution at the carbonyl carbon of aldehydes and ketones, often driven by the electrophilic nature of the carbon in the C=O bond. 1. Nucleophilic Addition Reactions of Carbonyl compounds: Addition of Hydrogen … Read more
Preparation of Carbonyl compounds Definition Preparation of carbonyl compounds refers to the chemical processes used to synthesize aldehydes and ketones, which are organic compounds containing the carbonyl group (C=O). 1. Oxidation of Alcohols Aldehydes: Primary alcohols can be selectively oxidized to aldehydes using mild oxidizing agents such as pyridinium chlorochromate (PCC) or Dess-Martin periodinane. Ketones: … Read more
Carbonyl compounds Definition Carbonyl compounds are organic compounds that contain a carbonyl group (C=O) as their functional group. The two major classes are: Physical Properties Molecular Structure: The carbonyl group consists of a carbon atom double-bonded to an oxygen atom, creating a site of high electron density. In aldehydes, the carbonyl group is bonded to … Read more
Carbonyl compounds (Aldehydes and ketones) are a significant class of organic compounds, including aldehydes and ketones, characterized by the presence of a carbonyl group (C=O). This group, comprising a carbon atom double bonded to an oxygen atom, contributes to their reactivity and polarity. Aldehydes and ketones play vital roles in various industrial and synthetic applications due … Read more
Solubility Expressions is a fundamental concept in physical pharmaceutics that influences the formulation, efficacy, and bioavailability of drugs. Understanding the solubility of drugs is crucial for developing effective pharmaceutical products. Solubility can be expressed in various ways, depending on the context and the required precision: Qualitative Solubility Expressions: Very Soluble: Less than 1 part solvent … Read more
Cyclobutene is a four-membered ring with one double bond. The presence of the double bond makes it reactive in ways similar to other alkenes, but the ring strain also plays a significant role in its reactivity. Hydrogenation of Reactions of Cyclobutene: Cyclobutene can be hydrogenated to form Cyclobutane. This reaction reduces the double bond, increasing … Read more
Propylene Glycol Definition Propylene glycol is a synthetic organic compound with the chemical formula C₃H₈O₂. It is a colorless, odorless, slightly viscous liquid that is hygroscopic (absorbs water) and miscible with water, acetone, and chloroform. Structure: Chemical Formula: C₃H₈O₂ Molecular Structure: Contains a three-carbon chain with two hydroxyl groups (-OH) attached to the first and … Read more
Glycerol (Glycerin) Definition Glycerol, also known as Glycerin (or Glycerine), is a simple polyol compound with the molecular formula C₃H₈O₃. It is a colorless, odorless, viscous liquid that is sweet-tasting and non-toxic. It contains three hydroxyl (–OH) groups, which makes it highly hydrophilic (water-attracting) and soluble in water. Structure: Chemical Formula: C₃H₈O₃ Molecular Structure: Consists … Read more
Benzyl Alcohol Definition Benzyl alcohol is an aromatic alcohol with the chemical formula C₆H₅CH₂OH. It consists of a benzene ring (C₆H₅–) attached to a methylene group (–CH₂–), which in turn is bonded to a hydroxyl group (–OH). Structure: Chemical Formula: C₆H₅CH₂OH Molecular Structure: Contains a benzene ring (C₆H₅-) attached to a methanol group (-CH₂OH). Geometry: … Read more
Cetostearyl Alcohol Definition Cetostearyl Alcohol is a white, waxy solid that functions primarily as an emulsifying agent, thickener, and emollient in topical products. It is categorized as a nonionic surfactant and fatty alcohol. Structure: Chemical Formula: A mixture of cetyl alcohol (C₁₆H₃₃OH) and stearyl alcohol (C₁₈H₃₇OH). Molecular Structure: Long-chain fatty alcohols, where cetyl alcohol has … Read more
