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.
A functional group is a group of atoms in a molecule with distinctive chemical properties, regardless of the other atoms in the molecule. The atoms in a functional group are linked to each other and to the rest of the molecule by covalent bonds. For repeating units of polymers, functional groups attach to their nonpolar core of carbon atoms and thus add chemical character to carbon

The preparation of stable α-iodo-functionalized ylides has the same limitations encountered with the brominated analogues. Ylide Ph 3 P CHI was prepared by several routes from either (Ph 3 PCH 2 I)X employing Alkyl groups are weakly ring-activating groups, as their electron-donating ability stems only from weak inductive effects. Substituents with heteroatoms connected to the aromatic ring are significantly more ring-activating than alkyl groups, because resonance electron-donating effects are possible. Before answering the question it is good to understand what goes into the making of a hydrogen bond.

The protective group is temporarily attached to decrease reactivity so that the protected functional group does not react under synthetic conditions to which the molecule is subjected in one or more subsequent steps. Patai’s Chemistry of Functional Groups is much more than just data. It provides detailed insights, review sand overviews on each functional group featured. This depth of content is the strength of the series as well as its broad coverage of techniques, methods, theory and applications.

Acetoxy group, abbreviated AcO or OAc, preferred IUPAC name acetyloxy, is a chemical functional group of the structure CH3-C-O-. It differs from the acetyl group CH3-C- by the presence of one additional oxygen atom. The name acetoxy is the short form of acetyl-oxy.
