The bond dissociation energies of X2, Y2 and XY are in the ratio of 1 : 0.5 : 1. H for the formation of XY is - -200 kJ mol-1. The bond dissociation energy of X2 will he
800 kJ mol-1
100 kJ mol-1
200 kJ mol-1
400 kJ mol-1
As we learnt that
Bond dissociation enthalpy -
It is the average of enthalpy required to dissociate the said bond present in different gaseous compound in to free atoms in gaseous state.
- wherein

100 kJ mol-1
This is incorrect.
Option 3)
200 kJ mol-1
This is incorrect.
Option 4)
400 kJ mol-1
This is incorrect.
