Identify and name functional groups in compounds. Amines are characterized by nitrogen atoms with single bonds to hydrogen and carbon. Saccharin is one of the additives that is usually added to the Watts bath in the electroplating process as a grain refiner. Some compounds contain multiple carboxylic acids within a single molecule. As we progress in our study of organic chemistry, it will become extremely important to be able to quickly recognize the most common functional groups, because they are the key structural elements that define how organic molecules react. 565574. 353358. One of the most important properties of amines is that they are basic, and are readily protonated to form ammonium cations. Electrochem., 1991, vol. The cis and trans forms of a given alkene are different molecules with different physical properties because, as we will learn in chapter 2, there is a very high energy barrier to rotation about a double bond. In order to produce nanostructural materials, some additives are used as grain refiners. In an aldehyde, the carbonyl carbon is bonded on one side to a hydrogen, and on the other side to a carbon. In an ether functional group, a central oxygen is bonded to two carbons. Starting in 1907, the United States Food and Drug Administration began investigating saccharin as a result of the Pure Food and Drug Act. Mater. Coat. 57435574.
