Naming Hydrates

The Greek prefixes used in naming hydrates for numbers 1/2 through 10 are as follows: 1/2: hemi-1: mono-2: di-3: tri-4: tetra-5: penta-6: hexa-7: hepta-8: octa-9: nona-10: deca-A hydrate that has lost water is referred to as an anhydride An anhydride can normally lose water only with significant heating A substance that no longer contains any

Acid Anhydrides

An Acid anhydride can be defined as a non-metal oxide which forms an acidic solution when reacted with water In organic chemistry it is a functional group consisting of 2 acyl groups combined together by an Oxygen atom The non-metals which are capable of reacting with water are only called as Acid anhydrides and non-metals that do not react with water are not acids

plz explain IUPAC naming system of acid anhydrides and

Symmetrical acid anhydrides are named by replacing acid in the name of the corresponding acid with anhydride For example: IUPAC name of the compound given below is propanoic anhydride Unsymmetrical acid anhydrides are named by first naming each component carboxylic acid alphabetically arranged (without the word acid) followed by spaces and then the word anhydride

Carboxylic Acids and Derivatives

Naming Carboxylic Acids The carboxylic acid group does not receive a number in the name because it is a terminal functional group Anhydrides are named by replacing acid with anhydride in the name of the corresponding carboxylic acid if the anhydride is formed from only one type of carboxylic acid If the anhydride is not symmetrical both carboxylic acids are

Carboxylic Acids Esters and Acyl Chlorides

Naming carboxylic acids • name the alkyl group then replace the final 'e' with 'oic acid' • remember that the carbon in the -COOH group is part of the alkyl chain for naming purposes so: HCOOH is methanoic acid CH 3COOH is ethanoic acid etc C 6H 5COOH is benzoic acid • the -COOH group can only go on the end of a chain so no numbering is required to identify its

Dicarboxylic acid

So succinic acid will yield succinic anhydride For acids with carboxylic groups at position 1 and 6 this dehydration causes loss of carbon dioxide and water to form a cyclic ketone for example adipic acid will form cyclopentanone Derivatives As for monofunctional carboxylic acids derivatives of the same types exist However there is the added complication that either one or
