,Ether
Ester
Amine
Aldehyde
Ketone An organic compound with a carbonyl group of which the carbon atom is
bonded to two other carbons.
Alkoxy is an -OR group, an alkyl (or aryl) groupatttached to an oxygen atom.
Alkyl group
Carbonyl carbon atom with a double bond to an oxygen atom
,Hydroxyl A functional group consisting of a hydrogen atom joined to an oxygen atom by
a polar covalent bond. Molecules possessing this group are soluble in water
and are called alcohols.
Acetyl In organic chemistry, acetyl is a functional group, the acyl with chemical
formula CH3CO. It is sometimes represented by the symbol Ac (not to be
confused with the element actinium). The acetyl group contains a methyl group
single-bonded to a carbonyl.
Gem-/Vic- Vicinal on 2 different adjacent carbons
Geminal- on same carbon
Tosyl a compound containing the functional group -SO3C6H4CH3, derived from
toluenesulfonic acid.
Mesyl a compound containing the functional group -SO3CH3, derived from
methanesulfonic acid.
Carboxylic Acid
Amide (think of amino acid strucutre)
Anhydride A functional group containing two carbonyls separated by an oxygen atom
(RCOOCOR); often the condensation dimer of a carboxylic acid.
, Aryl organic halide in which the halogen atom is attached to an aromatic ring, such
as a benzene ring
Halogens (fluorine, chlorine, bromine, iodine, astatine) are nonmetal elements
that are highly electronegative and reactive.
Benzyl benzyl is the substituent or molecular fragment possessing the structure
C6H5CH2-. Benzyl features a benzene ring attached to a CH2 group.
Hydrazine
Vinyl vinyl or ethenyl is the functional group −CH=CH2, namely the ethylene (IUPAC
ethene) molecule (H2C=CH2) minus one hydrogen atom. The name is also used
for any compound containing that group, namely R−CH=CH2 where R is any
other group of atoms.
Allyl An allyl group is a substituent with the structural formula H2C=CH-CH2R,
where R is the rest of the molecule
Nitrile A nitrile is an organic chemical that contains a cyano functional group (subunit),
CN-, in which the carbon and nitrogen atoms have a triple bond i.e. C≡N-. The
general chemical formula of a nitrile is RCN, where R is the organic group.
