Chloronium ion
Comment: This is not remotely close enough to what is needed for a Wikipedia article. You really should not expect someone else to rewrite it for you, we are all volunteers with much to do. I suggest looking at other articles such as Chloride. You will need to find more for notability as there is already the article Halonium ion. Ldm1954 (talk) 11:39, 16 August 2026 (UTC)
- Comment: Hi there! For help with adding in-text citations, you can check out Wikipedia's guides. This guide describes how to add them using Source Editor, while this one shows how to add them in Visual Editor. If you need additional support, feel free to reach out to me or the Teahouse.

(this is basically complete now, you can make this an article so it can be expanded by others, i dont think i have time to expand it and i dunno on what other topics i could expand it)

The chloronium ion makes part of the halonium ions, an example of molecule that cointain it is [H
2Cl]+
, (mostly known as chloranium and shown on the images) being that molecule is inorganic, its found in interstellar space, and its the protonated form of hydrogen chloride.
The neutral form of the monoatomic chloronium ion is obviously the monoatomic chlorine.
Salts
There are stable salts of it, mostly uses carborane acid and chlorane (HCl), chloronium ions forms in solutions of dichloromethane of the H(CHB
11Cl
11) acid.
H(CHB
11Cl
11) reacts with chloroalkanes, and the reaction produces dialkylchloronium salts, and they are stable at room temperature.
Dimethylchloronium ions decompose into CH
3Cl and sublimable CH
3(CHB
11Cl
11), providing a synthetic route to a electrophylic methylating agent.
formation
one of the ways it can form is by mixing hydrogen chloride on a strong acid like Magic acid, but it'll give just the simplest form, the [H2Cl]+ it usually takes form as a intermediate 3 membered bridge during electrophilic halogenation reactions in alkenes when they’re treated with Cl2 (alkenes can also be treated with Br2 and I2, but this is the chloronium page and not Halonium page to discuss about the other ones)[1] [2][3]
