2-Butyne (dimethylacetylene, crotonylene or but-2-yne) is an alkyne with chemical formula CH 3 C≡CCH 3. Produced artificially, it is a colorless, volatile, pungent liquid at standard temperature and pressure .
The C≡C bond distance of 118 picometers (for C 2 H 2) is much shorter than the C=C distance in alkenes (132 pm, for C 2 H 4) or the C–C bond in alkanes (153 pm). [3] Illustrative alkynes: a, acetylene, b, two depictions of propyne, c, 1-butyne, d, 2-butyne, e, the naturally occurring 1-phenylhepta-1,3,5-triyne, and f, the
Isobutylene (or 2-methylpropene) is a hydrocarbon with the chemical formula (CH 3) 2 C=CH 2. It is a four-carbon branched alkene (olefin), one of the four isomers of butylene . It is a colorless flammable gas, and is of considerable industrial value.
The hexynes are a subgroup from the group of alkynes.It consists of several isomeric compounds having the formula C 6 H 10.. The linear and branched members are: 1-Hexyne (n-butylacetylene)
Bromoethane, also known as ethyl bromide, is a chemical compound of the haloalkanes group. It is abbreviated by chemists as EtBr (which is also used as an abbreviation for ethidium bromide ). This volatile compound has an ether-like odor.
n-Butylamine is an organic compound (specifically, an amine) with the formula CH 3 (CH 2) 3 NH 2. This colourless liquid is one of the four isomeric amines of butane, the others being sec-butylamine, tert-butylamine, and isobutylamine. It is a liquid having the fishy, ammonia-like odor common to amines. The liquid acquires a yellow color upon ...
It is somewhat soluble in water and readily evaporates into the air. Bromoform is the main trihalomethane produced in beachfront salt water swimming pools with concentrations as high as 1.2 ppm (parts per million). Concentrations in freshwater pools are 1000 times lower. [9] Occupational skin exposure limits are set at 0.5 ppm. [10]
tert-Butylamine (also erbumine and other names) is an organic chemical compound with the formula (CH 3) 3 CNH 2.It is a colorless liquid with a typical amine-like odor. tert-Butylamine is one of the four isomeric amines of butane, the others being n-butylamine, sec-butylamine and isobutylamine.
