The general chemical equation for the hydration of alkenes is the following: RRC=CH 2 + H 2 O → RRC(OH)-CH 3. A hydroxyl group (OH −) attaches to one carbon of the double bond, and a proton (H +) adds to the other. The reaction is highly exothermic. In the first step, the alkene acts as a nucleophile and attacks the proton, following ...
Hexane (/ ˈ h ɛ k s eɪ n /) or n-hexane is an organic compound, a straight-chain alkane with six carbon atoms and the molecular formula C 6 H 14. [ 7 ] Hexane is a colorless liquid, odorless when pure, and with a boiling point of approximately 69 °C (156 °F).
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. [1] Structure of the coordination complex NbCl 3 (dimethoxyethane)(3-hexyne). [2]
1-Hexyne can be prepared by the reaction of monosodium acetylide with butyl bromide: [1] NaC 2 H + BrC 4 H 9 → HC 2 C 4 H 9 + NaBr. Its reactivity illustrates the behavior of terminal alkylacetylenes. The hexyl derivative is common test substrate because it is conveniently volatile. It undergoes deprotonation at C-3 and C-1 with butyl lithium:
Water-reactive substances [1] are those that spontaneously undergo a chemical reaction with water, often noted as generating flammable gas. [2] Some are highly reducing in nature. [ 3 ] Notable examples include alkali metals , lithium through caesium , and alkaline earth metals , magnesium through barium .
2-Hexyne can be semihydrogenated to yield 2-hexene or fully hydrogenated to hexane. [3] With appropriate noble metal catalysts it can selectively form cis-2-hexene. [4] 2-Hexyne can act as a ligand on gold atoms. [5] With strong sulfuric acid, the ketone 2-hexanone is produced. However this reaction also causes polymerization and charring. [6]
1-Hexanol (IUPAC name hexan-1-ol) is an organic alcohol with a six-carbon chain and a condensed structural formula of CH 3 (CH 2) 5 OH. This colorless liquid is slightly soluble in water, but miscible with diethyl ether and ethanol.
