2,2-Dimethylbutane, trivially known as neohexane at William Odling's 1876 suggestion, [4] is an organic compound with formula C 6 H 14 or (H 3 C-) 3-C-CH 2-CH 3. It is therefore an alkane , indeed the most compact and branched of the hexane isomers — the only one with a quaternary carbon and a butane (C 4 ) backbone.
In Figure 6, 2-chloro-2,3-dimethylbutane is stabilized through hyperconjugation from electron donation from σ C-H into σ* C-Cl, but both C–H and C–Cl bonds are weakened. A molecular orbital diagram shows that the mixing of σ C–H and σ* C–Cl in 2-chloro-2,3-dimethylbutane lowers the energy of both the orbitals (Figure 7).
The R−C(=O)O part is then named as a separate word based on the carboxylic acid name, with the ending changed from "-oic acid" to "-oate" or "-carboxylate" For example, CH 3 CH 2 CH 2 CH 2 COOCH 3 is methyl pentanoate, and (CH 3) 2 CHCH 2 CH 2 COOCH 2 CH 3 is ethyl 4-methylpentanoate.
Names Preferred IUPAC name. ... Isobutyl chloride (1-chloro-2-methylpropane) is an organochlorine compound. It is a chlorinated derivative of isobutane. Synthesis
3D structure A Newman projection is a drawing that helps visualize the 3-dimensional structure of a molecule. [ 1 ] This projection most commonly sights down a carbon-carbon bond, making it a very useful way to visualize the stereochemistry of alkanes.
1-Chlorobutane is an alkyl halide with the chemical formula CH 3 (CH 2) 3 Cl. It is a colorless, flammable liquid. It is a colorless, flammable liquid. Preparation and reactions
1,4-Dichlorobutane is a chloroalkane with the molecular formula (CH 2 CH 2 Cl) 2. It is one of several structural isomers of dichlorobutane. They are all colorless liquids of low flammabiltity and of interest for specialized synthetic uses.
Names Preferred IUPAC name (2E)-1-Chlorobut-2-ene. Other names 1-Chloro-2-butene, 1-chlorobut-2-ene, 2-butenyl chloride, gamma-methylallyl chloride. Identifiers
