WebJan 23, 2024 · Functional groups A. In organic chemistry, functional groups are specific groups of atoms within molecules arranged in a specific manner. The following tables list common functional groups arranged by heteroatom. The symbols R, R', R'' and R''' usually denote a hydrocarbon chain or a hydrogen but can sometimes be any group of atoms.

WebJul 20, 2024 · The deprotonated forms of alcohols, phenols, and thiols are called alkoxides, phenolates, and thiolates, respectively. A protonated alcohol is an oxonium ion. In an ether functional group, a central oxygen is bonded to two carbons. WebIn this experiment, racemic (R + S)-phenylsuccinic acid is separated (resolved) into optically active enantiomers in a sequence of two steps. First, we exploit its chemical nature (it is an acid) by treating it with an optically active biologically produced base, L-proline. This is an ordinary acid - base reaction that produces a salt.
WebTwo protons are transferred from the phenylsuccinic acid to the proline. One proline has a position available for one extra proton, so the two protons end up on two different prolines. Because protons have +1 charge, each proline is cationic. The phenylsuccinic acid gave up two positives, so it is a dianion.
