  • CARBOXYLIC ACID - 608 Words
     CARBOXYLIC ACID Introduction: Organic compounds containing (–C(O)–OH) as a functional group are called carboxylic acids. The –C (O)-OH group which itself is made up of a carbonyl group (>C=O) and a hydroxyl group (-OH) is called a carboxyl group (carb from carbonyl and oxyl from hydroxyl group). Carboxylic acid may be an aliphatic or an aromatic depending upon whether –C–OH is attached to an alkyl group ( or a hydrogen atom) or an aryl group. Their general formulas are; ALIPHATIC...

The general formula of a carboxylic acid is R-COOH, where R is some monovalent functional group. A carboxyl group (or carboxy) is a functional group consisting of a carbonyl (RR'C=O) and a hydroxyl (R-O-H), which has the formula -C(=O)OH, usually written as -COOH or -CO2H. Carboxylic acids are Brønsted-Lowry acids because they...

    Acetyl chloride, CH3COCl, also known as ethanoyl chloride or acyl chloride, is an acid chloride derived from acetic acid. It belongs to the class of organic compounds called acyl halides. It is a colorless liquid. Acetyl chloride does not exist in nature, because contact with water would hydrolyze it into acetic acid and hydrogen chloride. In fact, if handled in open air it gives off white smoke owing to the hydrolysis from the moisture in the air. The "smoke" is actually small droplets of...

They are derived by reacting an oxo acid with a hydroxyl compound such as an alcohol or phenol. Esters are usually derived from an inorganic acid or organic acid in which at least one -OH (hydroxyl) group is replaced by an -O-alkyl (alkoxy) group, and most commonly from carboxylic acids and alcohols. That is, esters are formed by condensing an acid...

Instead of using acetic acid, acetic anhydride was used as solvent since the anhydride reacting with water to form acetic acid tends to drive the reaction to the right. It results from the elimination of a molecule of water from two molecules of acetic acid (see Fig. 11.2). Figure 11.3...
