Q. From the following data, calculate the bond enthalpies of $C - C$ (in $kJ$ ) Enthalpy of formation of $CH _{3} CN =87.86$, Enthalpy of formation of $C _{2} H _{6}=-83.68$. Enthalpy of transition of graphite to diamond $=1.8$, Bond enthalpy of $C-C$ bond in diamond $=358.92$ Enthalpy of dissociation of $N _{2}=945.58$, Enthalpy of dissociation of $H _{2}=435.14$ Bond enthalpy of $C - H$ bond $=414.22$ [All data in $kJ\, mol ^{-1}$ ]
