Pi and sigma bond

Postby SMIYAZAKI_1B » Tue Feb 11, 2020 7:55 pm

When solving the bond enthalpies, does the sigma bond break or the pi bond in double bonds? I know Dr. Lavalle talked about it but I wrote both so it’s confusing.

We don't know what the specific bond enthalpy for breaking a pi bond. So we break both and record the bond enthalpy for a, say, carbon-carbon double bond as different from a single bond
