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
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.
The first step is the liquid- or vapour-phase chlorination of butadiene to a mixture of 3,4-dichlorobut-1-ene and 1,4-dichlorobut-2-ene (both isomers). In the second step, the mixture of 1,4-dichlorobut-2-ene and 3,4-dichlorobut-1-ene is isomerized to 3,4-dichlorobut-1-ene by heating to temperatures of 60–120 °C in the presence of a catalyst.
tert-Amyl alcohol (TAA) or 2-methylbutan-2-ol (2M2B), is a branched pentanol. Historically, TAA has been used as an anesthetic [ 3 ] and more recently as a recreational drug . [ 4 ] TAA is mostly a positive allosteric modulator for GABA A receptors in the same way as ethanol . [ 5 ]
(ch 3) 3 coh + hcl → (ch 3) 3 ccl + h 2 o Because tert -butanol is a tertiary alcohol, the relative stability of the tert -butyl carbocation in the step 2 allows the S N 1 mechanism to be followed, whereas a primary alcohol would follow an S N 2 mechanism.

Chloroprene (IUPAC name 2-chlorobuta-1,3-diene) is a chemical compound with the molecular formula CH 2 =CCl−CH=CH 2. [3] Chloroprene is a colorless volatile liquid, almost exclusively used as a monomer for the production of the polymer polychloroprene, better known as neoprene , a type of synthetic rubber .
