What are protective groups? a protective group (also referred to as "protecting group") is a reversably formed derivative of an existing functional group in a molecule., property: unit: value / range: preferred: molar volume v m: ml mol-1: 85.8 - 91.6: 87.8: density ρ: g ml-1: 0.94 - 1.00: 0.94: solubility parameter δ: mpa 1/2: 16.9 ....

Functional groups are groups of atoms found within molecules that are involved in the chemical reactions characteristic of those molecules. functional groups can pertain to any molecules, but you will usually hear about them in the context of organic chemistry.the symbol r and r' refer to an attached hydrogen or hydrocarbon side chain or sometimes to any group of atoms., in an electrophilic aromatic substitution reaction, existing substituent groups on the aromatic ring influence the overall reaction rate or have a directing effect on positional isomer of the products that are formed. an electron donating group (edg) or electron releasing group (erg, z in structural formulas) is an atom or functional group that donates some of its electron density into a ....

One of the key properties of the oh group is that is is readily deprotonated. this occurs because hydrogen and oxygen have different electronegativity values.group that contain this functional group tend to have higher melting and boiling points than compounds that lack the group., in organic chemistry, the phenyl group or phenyl ring is a cyclic group of atoms with the formula c 6 h 5.phenyl groups are closely related to benzene and can be viewed as a benzene ring, minus a hydrogen, which may be replaced by some other element or compound to serve as a functional group.phenyl groups have six carbon atoms bonded together in a hexagonal planar ring, five of which are ....

Electron withdrawing group are one which produce the negative inductive effect while donating group produce the positve effects. its means the same as what mrsemmapeel has mentioned.
