List of top Chemistry Questions on Chemical bonding and molecular structure asked in NEET (UG)

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:

Given below are two statements:
Statement I: A hypothetical diatomic molecule with bond order zero is quite stable.
Statement II: As bond order increases, the bond length increases.
In the light of the above statements, choose the most appropriate answer from the options given below:
