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.

Solutions

Expert Solution

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.
