# Can a Hydrogen Radical form in a chemical reaction?

Original question: During kolbe electrolysis of Formic acid, H2 is released at which electrode?

What I thought: H2 will form at cathode due to reduction of water. But will the Formic acid decompose to give H2 and CO2 by radical mechanism?

My doubt: Does H radical form in chemical reactions?

• Yes a H radical form can form in chemical reactions. However it is extremely reactive and will exist for only a fleeting amount of time. – MaxW Apr 2 '19 at 17:30
• @MaxW will there be release of H2 at the anode then? – Groverkss Apr 2 '19 at 17:31

• $\ce{HCOOH -> CO2 + H2}$ – MaxW Apr 2 '19 at 17:42
• @MaxW That is the problem I am having. This is only possible if H radical forms in the reaction. I'm not sure if it will work as standard kolbe reaction. – Groverkss Apr 2 '19 at 17:43
