Cycloheptatrienyl cation
WebKa is the value of the equilibrium constant for the ionization of an acid in water. The greater the Ka, the more of the acid ionizes, and the stronger the acid. Most common weak acids have Ka values ranging from 10^-2 to 10^-14. A Ka value of 10^-2 means that an acid is stronger than one with a Ka of 10^-12.

In addition, the single methylene group ( C H X 2) sticks out of the plane of the rest of the molecule. (On the other hand, removing a hydride ion H X − from the C H X 2 group leaves the tropylium ion C X 7 H X 7 X ...
The tropylium ion or cycloheptatrienyl cation is an aromatic species with a formula of [C7H7] . Its name derives from the molecule tropine from which cycloheptatriene (tropylidene) was first synthesized in 1881. Salts of the tropylium cation can be stable, even with nucleophiles of moderate strength e.g., tropylium tetrafluoroborate and tropylium bromide (see below). Its bromide and chloride salts can be made from cycloheptatriene and bromine or phosphorus pentachloride, … Webcycloheptatrienyl catio Name two of the three common allotropes of carbon. diamond; graphite; fullerenes (like buckminsterfullerene) What is the bond order of the carbon-carbon bonds in benzene? 1.5 Describe the occupied p molecular orbitals in …
Cycloheptatriene (CHT) is an organic compound with the formula C7H8. It is a closed ring of seven carbon atoms joined by three double bonds (as the name implies) and four single bonds. This colourless liquid has been of recurring theoretical interest in organic chemistry. It is a ligand in organometallic chemistry and a building block in organic synthesis. Cycloheptatriene is not aromatic, as reflected by the nonplanarity of the methylene bridge (-CH2-) with respect to the other atoms…
