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

The intermolecular potential energy for the moleculesA ,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. D is more electronegative than other atoms.
  4. A-B has the stiffest bond.

Solution

Bond enthalpy of AB bond is highest so A-B bond is more strong and B is highest electronegative atom. Order of bond length ⇒A-A<A-B<A-C<A-D
