8.2 Organic chemistry isomerism — Chemistry STD 11 Science — Question

$xMnO_4^ - \, + \,y{C_2}O_4^{2 - }\, + \,z{H^ + }\, \rightarrow $$\,xM{n^{2 + }} + 2yC{O_2} + \frac{z}{2}{H_2}O$

The value's of $x, y$ and $z$ in the reaction are, respectively :

$(i)\, {\Delta _f}{H^o}$ of $N_2O$ is $82\, kJ\, mol^{-1}$

$(ii)$ Bond energies of $N \equiv N,N = N,O = O$ and $N = O$ are $946, 418, 498$ and $607\, kJ\, mol^{- 1}$ respectively

The resonance energy of $N_2O$ is......$kJ$
