If there are multiple functional groups of the same type, either prefixed or suffixed, the position numbers are ordered numerically (thus ethane-1,2-diol, not ethane-2,1-diol.) The N position indicator for amines and amides comes before "1", e.g., CH 3 CH(CH 3)CH 2 NH(CH 3) is N,2-dimethylpropanamine.
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).
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.

This is because 2-chlorobutane possesses two different sets of β-hydrogens at the first and third carbons respectively, resulting in 1-butene or 2-butene. It is important to note that as a secondary alkyl halide, both E2 and Sn2 reactions are equally likely when reacting with a substance that can act as both a base and a nucleophile.
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.

1,4-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.
