# The intermolecular potential energy for the molecules A

Question:

The intermolecular potential energy for the molecules $A$, $B, C$ and $D$ given below suggests that :

1. A-D has the shortest bond length

2. A-A has the largest bond enthalpy

3. $\mathrm{D}$ is more electronegative than other atoms

4. A-B has the stiffest bond

Correct Option: , 4

Solution:

A-B bond has highest intermolecular potential energy among the given molecules. Hence, it is strongest bond and has maximum bond enthalpy.
