Question

Identify the correct orders against the property mentioned:
A. H$_2$O $>$ NH$_3$ $>$ CHCl$_3$ - dipole moment
B. XeF$_4$ $>$ XeO$_3$ $>$ XeF$_2$ - number of lone pairs on central atom 
C. O–H $>$ C–H $>$ N–O - bond length 
D. N$_2$>O$_2$>H$_2$ - bond enthalpy 
Choose the correct answer from the options given below:

• A. B, D only
• B. A, C only
• C. B, C only
• D. A, D only

Hint:

The dipole moment increases with the difference in electronegativity and the molecular geometry. Lone pairs on the central atom increase as we go from simpler molecules like XeF\(_2\) to more complex ones like XeF\(_4\).
