The intermolecular potential energy for the molecules A, B, C and D given below suggests that : (A) A-D has the shortest bond length (B) A-A has the largest bond enthalpy (C) D is more electronegative

Question

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

(A) A-D has the shortest bond length
(B) A-A has the largest bond enthalpy
(C) D is more electronegative than other atoms.
(D) A-B has the stiffest bond.

Prashant Kotian · Accepted Answer

Correct answer: D. 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
