WebSep 22, 2015 · The $\ce{C-C}$ bonds in benzene are $\mathrm{140~pm}$ long which puts them in between single bonds and double bonds (given at $\mathrm{147-154~pm}$ and $\ce{134-135~pm}$ respectively, sourced from here and here) as expected.However, since the two resonance structures for benzene contribute equally, leading to six identical …

WebIf the bond energy of a single P−P bond is 200 kJ mol¯ 1, what is the energy of the PP triple bond in P 2? Solution: Say you break all 6 P−P bonds in P 4, that is 6 x 200 = +1200. 1200 − 217 = 983 which is released when two P≡P bonds form. So 983 / 2 = bond energy of a P≡P bond.
