Clarification[edit]
The introduction puts forward the following definition:
- A carbocation (IPA pronunciation: [kɑ(r)'bəʊkæt'aɪ.ɒn]) is an ion with a positively-charged carbon atom.
In the definition section another definition is put forward:
- In present day chemistry a carbocation is any positively charged carbon atom.
The first definition would accept a any polyatomic ion with a charged carbon atom as a carbocation... perhaps if "an ion with" is removed it would be more clear?
Mergers need to be made!
- explain why you posted the merge notices without discussion here and why did you not sign your post. V8rik 20:48, 15 February 2007 (UTC)
- I added links to the other articles and investigated how carbocations are discussed in a bunch of university level textbooks . I hope that clears up the issue. V8rik 21:58, 24 February 2007 (UTC)
Do we need the carbonium ion image?[edit]
Do we need the carbonium ion image?. This will only confuse readers who are mostly interested in trivalent carbon. Carbonium ion has its own page. Lets try to limit the information creep. V8rik (talk) 17:23, 11 June 2010 (UTC)
- it is especially confusing since the Definition specifically tells us that "carbonium ion" is an antiquated term that some textbooks cling on to. I would expect to see the title changed to "carbenium ion". Zorgster (talk) 14:54, 10 March 2013 (UTC)
Merge to Carbenium ion[edit]
Although carbocations are classified to carbenium ion (R3C+) or carbonium ion (R5C+), this article does not mainly describe R5C+ but R3C+. Therefore, most of contents of this article should be merged to carbenium ion. --Nao1958 (talk) 21:02, 10 February 2013 (UTC)
Hydride affinities[edit]
In the hydride affinities section, the stability of various carbocations is shown in a table. What I find strange is that all the bond energies described in this section are given in kcal/mol; this is pretty much never used in chemistry textbooks as a measure of bond strength, they are almost always given in kJ/mol. It is likely that a student could look at this table, fail to note the units, and come away thinking that these affinities are much lower than they actually are; in fact I almost did, until I thought to myself that the energies involved looked a bit small, and only then I noticed the units.
Could someone please convert the table to kJ/mol?
