- In chemistry,
ethanium or
protonated ethane is a
highly reactive positive ion with
formula C 2H+ 7. It can be
described as a
molecule of
ethane (C 2H 6)...

covalently bonded to five
hydrogen atoms. The
ethanium ion C2H+7 has been
characterized by
infrared spectroscopy. The isomers...
- such as CH+ 5 and HCO+ form
ethanium preferably to ethenium.) At room
temperature and in a
rarefied methane atmosphere,
ethanium slowly dissociates to ethenium...

occur with
extraordinarily high rates.
Carbonium ions such as
ethanium C 2H+ 7 have three-center two-electron bonds.
