3-Hexyne is the organic compound with the formula C 2 H 5 CCC 2 H 5. This colorless liquid is one of three isomeric hexynes. 3-Hexyne forms with 5-decyne, 4-octyne, and 2-butyne a series of symmetric alkynes. It is a reagent in organometallic chemistry.

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) 2-Hexyne (methylpropylacetylene) 3-Hexyne (diethylacetylene) 3-methylpent-1-yne; 4-methylpent-1-yne; 4-methylpent-2-yne; 3,3-dimethylbut-1-yne
In organic chemistry, hexene is a hydrocarbon with the chemical formula C 6 H 12.The prefix "hex" is derived from the fact that there are 6 carbon atoms in the molecule, while the "-ene" suffix denotes that there is an alkene present—two carbon atoms are connected via a double bond.
A 3D model of ethyne (), the simplest alkyneIn organic chemistry, an alkyne is an unsaturated hydrocarbon containing at least one carbon—carbon triple bond. [1] The simplest acyclic alkynes with only one triple bond and no other functional groups form a homologous series with the general chemical formula C n H 2n−2.
Alkanes with more than three carbon atoms can be arranged in various ways, forming structural isomers.The simplest isomer of an alkane is the one in which the carbon atoms are arranged in a single chain with no branches.
An attempt to quantify the 'softness' of a base consists in determining the equilibrium constant for the following equilibrium: BH + CH 3 Hg + ⇌ H + + CH 3 HgB. where CH 3 Hg + (methylmercury ion) is a very soft acid and H + (proton) is a hard acid, which compete for B (the base to be classified). Some examples illustrating the effectiveness ...
Due to the activated nature of the cyclic carbon–carbon triple bond, many alkyne addition-type reactions such as the Diels–Alder, 1,3-dipolar cycloadditions and halogenation may be performed using very mild conditions and in the absence of the catalysts frequently required to accelerate the transformation in a non-cyclic system. In addition ...
This reaction is used to protect alkynes: the alkyne is either converted with acetone to a 2-hydroxyprop-2-yl-alkyne or a protected alkyne can be directly synthesized using the commercially available 2-methyl-3-butyn-2-ol as an alkyne source. [5]
