The Ph 3 C-H bond is relatively weak, with a bond dissociation energy (BDE) of 81 kcal/mol, or about 24 kcal/mol less than methane. [4] Correspondingly, triphenylmethane is mildly acidic, with a pK a of 33.297.
Prehnitene is one of three isomers of tetramethylbenzene, the other two being isodurene (1,2,3,5-tetramethylbenzene) and durene (1,2,4,5-tetramethylbenzene). [1] It is a relatively easily oxidized benzene derivative, with E 1/2 of 2.0 V vs NHE.
The tetramethylbenzenes constitute a group of substances of aromatic hydrocarbons, which structure consists of a benzene ring with four methyl groups (–CH 3) as a substituent. [1] Through their different arrangement, they form three structural isomers with the molecular formula C 10 H 14. They also belong to the group of C 4-benzenes.
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 .
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]
(Fluoroform (CHF 3) cannot be prepared in this manner.) Chloroform is produced by heating mixtures of methane or methyl chloride with chlorine. Dichloromethane is a coproduct. [4] Bromochlorofluoromethane is one of the simplest possible stable chiral compounds, and is used for studies.
It undergoes deprotonation at C-3 and C-1 with butyl lithium: HC 2 C 4 H 9 + 2 BuLi → LiC 2 CH(Li)C 3 H 7 + 2 BuH. This reaction allows alkylation at the 3-position. [2] Catechol borane adds to 1-hexyne to give the 1-hexenyl borane. [3] 1-Hexyne reacts with diethyl fumarate to produce n-hexylsuccinic acid. [4]
3,3-Dimethylhexane is a colourless, odourless liquid, chemical compound in the family of hydrocarbons which has a formula of C 8 H 18. It is an isomer of octane , where two methylene hydrogens at the third position in a hexane molecule have been replaced with two methyl groups.
