# Selective bond breaking

Can a specific bond be broken by an engineered energy wave corresponding to the bond length?

For example, can we break the $\ce{C-N}$ bond and not the $\ce{C-H}$ in a hydrocarbon chain?

• Arguably, the entire realm of chemistry is nothing but selective bond breaking. So yes, this can be done, though the light with specially selected frequency is a relatively rare tool to use. May 7 '17 at 14:59

• @SatwikPasani Yeah, right, that too. May 7 '17 at 18:45
