QJEEM20Ch41ff: JEE Main 2020 Chemistry - Class 11 JEEM20Ch41ff Solution: The intermolecular potential energy for the molecules A, B, C…
The intermolecular potential energy for the molecules A, B, C and D given below suggests that : 
Multiple Choice Options
- A A-B has the stiffest bond
- B A-D has the shortest bond length
- C A-A has the largest bond enthalpy
- D D is more electronegative than other atoms
Step-by-Step Verified Solution
From the given graph, potential energy of A-B molecule is minimum.
Thus A-B bond is most stable as it requires more energy to dissociate and have strongest bond amongst these.
B = Most electronegative
D = Least electronegative
A - B = Shortest bond length
A - B = Largest bond enthalpy
Thus A-B bond is most stable as it requires more energy to dissociate and have strongest bond amongst these.
B = Most electronegative
D = Least electronegative
A - B = Shortest bond length
A - B = Largest bond enthalpy
