wintergreen | Introduction Organic compounds are those which contain carbon as well as a select other elements. An organic acid however‚ is an organic compound which contains acidic properties. An ester is an example of being a derivative of these organic acids. Esters can be prepared by the reaction of carboxylic acids and alcohols‚ with an inorganic acid used as a catalyst which is dubbed esterification. With o-hydrobenzoic acid‚ or salicylic acid‚ we are able to create acetylsalicylic

Esterification Lab Introduction Esters are classified as organic compounds commonly derived from carboxylic acids. They are compounded from the reaction of a carboxylic acid with an alcohol in the presence of a strong acid to be used as a catalyst. The formula that represents an ester is R-COO-R where both Rs’ are alkyl groups‚ one which is bonded to an oxygen‚ and the other to a carbon which is double bonded to 1 oxygen and single bonded to the other. Esters are named in almost a reverse fashion

Functional Groups of Organic Compounds A functional group is a specific arrangement of atoms in the HC derivative other than carbon and hydrogen. Literally‚ the functional group determines the functions of the particular HC derivative in chemical reactions. This means that the specific properties of the HC derivative are due to its functional group. Each functional group is attached to an alkyl radical (R). An alkyl radical is one H atom less than the given alkane. The alkyl radical (R) uses
