JEE Main 2020 — Chemical Bonding And Molecular Structure Question with Solution
From: JEE Main 2020 (Online) 4th September Morning Slot
Question
The intermolecular potential energy for the
molecules A, B, C and D given below suggests
that :
This question includes a diagram. The text above accompanies the figure.

Correct answer
AA-B has the stiffest bond
Step-by-step explanation
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
