An ester of a carboxylic acid. R stands for any group (typically hydrogen or organyl) and R ′ stands for any organyl group. In chemistry, an ester is a compound derived from an acid (organic or inorganic) in which the hydrogen atom (H) of at least one acidic hydroxyl group (−OH) of that acid is replaced by an organyl group (R ′).

2025年3月12日 · ester, any of a class of organic compounds that react with water to produce alcohols and organic or inorganic acids. Esters derived from carboxylic acids are the most common. The term ester was introduced in the first half of the 19th century by German chemist Leopold Gmelin.

2022年9月15日 · Identify the general structure for an ester. Use common names to name esters. Name esters according to the IUPAC system.

What is Ester? An ester is a chemical compound derived from an acid (organic or inorganic) in which at least one –OH hydroxyl group is replaced by an –O– alkyl (alkoxy) group.

2020年1月4日 · An ester is an organic compound where the hydrogen in the compound's carboxyl group is replaced with a hydrocarbon group. Esters are derived from carboxylic acids and (usually) alcohol. While carboxylic acid has the -COOH group, the hydrogen is replaced by a hydrocarbon in an ester.

2024年4月1日 · What is an ester in chemistry? A compound or a functional group derived from alcohol condensation and acid with simultaneous water loss. Carboxylic ester (also referred to as carboxylate ester; also simply called an ester), derived from carboxylic acid, is …

Many simple esters are pleasant-smelling liquids that are responsible for the fragrant odors of fruits and flowers. For example, methyl butanoate is found in pineapple oil, and isopentyl acetate is a constituent of banana oil. The ester linkage is also present in animal fats and in many biologically important molecules.

discuss the wide occurrence of esters in nature, and their important commercial uses, giving one example of an ester linkage in nature, and one example of a commercially important ester. write an equation to describe the hydrolysis of an ester under acidic or basic conditions.

2023年1月23日 · One of the partially-positive hydrogen atoms in a water molecule can be sufficiently attracted to one of the lone pairs on one of the oxygen atoms in an ester, forming a hydrogen bond. Dispersion forces and dipole-dipole attractions are also present.

Esterification is a chemical reaction in which an alcohol reacts with a carboxylic acid, acyl chloride, or acid anhydride to form an ester and a byproduct, typically water or hydrogen chloride.
