1-Chlorobutane is an alkyl halide with the chemical formula CH 3 (CH 2) 3 Cl. It is a colorless, flammable liquid. Preparation and reactions.
Pentanenitrile can be produced by heating 1-chlorobutane with sodium cyanide in dimethyl sulfoxide. This reaction takes about 20 minutes, keeping the temperature below 160 °C. The yield is about 93%. [2] Another way to get the substance is by heating valeraldehyde with hydroxylamine. [3] Pentanenitrile is contained in bone oil. [4]
Chlorobutanol (trichloro-2-methyl-2-propanol) is an organic compound with the formula CCl 3 C(OH)(CH 3) 2. The compound is an example of a chlorohydrin. The compound is a preservative, sedative, hypnotic and weak local anesthetic similar in nature to chloral hydrate. It has antibacterial and antifungal properties. [1]
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.
For esters such as ethyl acetate (CH 3 COOCH 2 CH 3), ethyl formate (HCOOCH 2 CH 3) or dimethyl phthalate that are based on common acids, IUPAC recommends use of these established names, called retained names. The "-oate" changes to "-ate." Some simple examples, named both ways, are shown in the figure above.
In organic chemistry, alkylidene is a general term for divalent functional groups of the form R 2 C=, where each R is an alkane or hydrogen. [1] They can be considered the functional group corresponding to mono- or disubstituted divalent carbenes (known as alkylidenes), [2] or as the result of removing two hydrogen atoms from the same carbon atom in an alkane.

The branching in 2-ethyl-1-butanol makes it harder to crystallize due to packing disruption, which results in a very low freezing point. Esters of 2-ethyl-1-butanol are similarly effected and it therefore finds application as a feedstock in the production of plasticizers and lubricants, where its presence helps reduce viscosity and lower freezing points.
