Lone pair? How come?[edit]
How come there is a lone pair of electrons in the figure? The carbon atom is positively charged. So, it should have only 3 valence electrons. The 3 single bonds have consumed all of them. So, there should be no unbounded valence electrons left, right?
In addition, if there is a lone pair, then there would be 4 electron domains around the carbon atom, leading to a tetrahedral arrangement. In that case, the ion's shape would be pyramidal, not planar!

- Oops, you are right. Will fix asasp. --Jorge Stolfi (talk) 14:42, 22 June 2013 (UTC)
Image is still incorrect[edit]
As stated in previous talk entry, the electron configuration in the image "File:Chemdg methenium 1pos.svg" is wrong. If the lone electron pair were removed it would be correct. — Preceding unsigned comment added by Dreymond (talk • contribs) 23:20, 6 April 2014 (UTC)
- I have now replaced the incorrect diagram by a correct one with no lone pair, which I found in the article on carbocation. Dirac66 (talk) 01:18, 19 May 2014 (UTC)
