Bond Enthalpy Questions

Identify the correct orders against the property mentioned:A. ${\text{H}}_2\text{O}>{\text{NH}}_3>{\text{CHCl}}_3$ – dipole momentB. ${\text{XeF}}_4>{\text{XeO}}_3>{\text{XeF}}_2$ – number of lone pairs on central atomC. $\text{O-H}>\text{C-H}>\text{N-O}$ – bond lengthD. ${\text{N}}_2>{\text{O}}_2>{\text{H}}_2$ – bond enthalpyChoose the correct answer from the options given below :

Given that bond energy of $\text{H—H}$ and $\text{Cl-Cl}$ is $430{\text{ kJ mol}}^{-1}$ and $240{\text{ kJ mol}}^{-1}$ respectively and $\Delta H_f$ for $\text{HCl}$ is $-90{\text{ kJ mol}}^{-1}$. The bond enthalpy of $\text{HCl}$ is:

Bond dissociation enthalpy of ${\text{H}}_2$, ${\text{Cl}}_2$ and $\text{HCl}$ are $434$, $242$ and $431\text{kJ/mol}$ respectively. Enthalpy of formation of $\text{HCl}$ is:
