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)...

methanium (CH+5) carbon is covalently bonded to five hydrogen atoms. The ethanium ion C2H+7 has been characterized by infrared spectroscopy. The isomers...

so they occur with extraordinarily high rates. Carbonium ions such as ethanium C 2H+ 7 have three-center two-electron bonds. Perhaps the best known and...

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...
