The H?X bond length is 105 pm and the H?Y bond length is 119 pm. What is true about the bonding in H?X and H?Y? Select the correct answer below:
Question 18 options:
There is greater orbital overlap between H and Y than between H and X
There is greater orbital overlap between H and X than between H and Y
H?Y is a stronger bond than H?X
The H?Y bond energy is greater than the H?X bond energy.
H-X bond length (105pm) is < H-Y bond length (119pm).
>There is greater orbital overlap between H and X than between H and Y: Correct. Because, more the bond length, more the distance between two nuclei and hence lesser the overlap.
> H-Y is a stronger bond than H-X: Incorrect. lesser the bond length stronger the bond.
> The H-Y bond energy is greater than the H-X bond energy: Incorrect. lesser the bond length stronger the bond and higher the bond energy.
