If two atoms A and B of a molecule are brought closer than their minimum inter-nuclear distance, then potential energy of the system
If two atoms A and B of a molecule are brought closer than their minimum inter-nuclear distance, then potential energy of the system
The correct option is B starts increasing
The explanation for the correct answer
(b) starts increasing
- The distance between two nuclei in a molecule is called inter-nuclear distance.
- On bringing the two atoms closer than their inter-nuclear distance, these electrons come closer to each other and also nucleus to nucleus closer so the potential energy of the system increases.
The explanation for the incorrect answer
(a) remains constant at a minimum value
When two atoms are brought close to their inter-nuclear distance, the electrons come closer to each other. Therefore, the potential energy does not remain constant at a minimum value.
(c) remains constant at maximum value
When two atoms are brought close to their inter-nuclear distance, the electrons come closer to each other. Therefore, the potential energy does not remain constant at a maximum value.
(d) starts decreasing
When two atoms are brought close to their inter-nuclear distance, the electrons come closer to each other and the potential energy starts to increase. Therefore, it does not decrease.
Therefore, If two atoms A and B of a molecule are brought closer than their minimum inter-nuclear distance, then the potential energy of the system starts increasing.
Hence, Option(b) is correct option.
