Butyl group. In organic chemistry, butyl is a four- carbon alkyl radical or substituent group with general chemical formula −C4H9, derived from either of the two isomers (n -butane and isobutane) of butane. The isomer n -butane can connect in two ways, giving rise to two "-butyl" groups: The second isomer of butane, isobutane, can also ...
Alkyl group. In organic chemistry, an alkyl group is an alkane missing one hydrogen. [1] The term alkyl is intentionally unspecific to include many possible substitutions. An acyclic alkyl has the general formula of −CnH2n+1. A cycloalkyl group is derived from a cycloalkane by removal of a hydrogen atom from a ring and has the general formula ...
tert-Butylbenzene is an organic compound classified as an aromatic hydrocarbon. Its structure consists of a benzene ring substituted with a tert -butyl group. It is a flammable colorless liquid which is nearly insoluble in water but miscible with organic solvents.
n-Butylbenzene is the organic compound with the formula C 6 H 5 C 4 H 9. Of two isomers of butylbenzene, n -butylbenzene consists of a phenyl group attached to the 1 position of a butyl group. It is a slightly greasy, colorless liquid. The synthesis of n -butylbenzene by the reaction of chlorobenzene and butylmagnesium bromide was one of the ...
(1) Fmoc-protected amino group, (2) benzyl ester protected carboxyl group and (3) tert-butyl ether protected phenolic hydroxyl group of Tyrosine. Orthogonal protection is a strategy allowing the specific deprotection of one protective group in a multiply-protected structure.
Butyl acrylate is an organic compound with the formula C4H9O2CCH=CH2. A colorless liquid, it is the butyl ester of acrylic acid. It is used commercially on a large scale as a precursor to poly (butyl acrylate). Especially as copolymers, such materials are used in paints, sealants, coatings, adhesives, fuel, textiles, plastics, and caulk.
A value. The A-value for a methyl group is 1.74 as derived from the chemical equilibrium above. This means it costs 1.74 kcal/mol (7.3 kJ/mol) of energy to have a methyl group in the axial position compared to the equatorial position. A-values are numerical values used in the determination of the most stable orientation of atoms in a molecule ...
n-Butyl acetate is an organic compound with the formula CH 3 CO 2 (CH 2) 3 CH 3. A colorless, flammable liquid, it is the ester derived from n- butanol and acetic acid . It is found in many types of fruit, where it imparts characteristic flavors and has a sweet smell of banana or apple.
