Consider the given figure showing the formation of `H_(2)^(+)` ion depending on intermuclear distance versus potential energy of the system.

Options

A. Curve -1 represents the most stable state of the system for `H_(2)^(+)` ion
B. Curve -2 represents the most stable state of the system for `H_(2)^(+)` ion
C. Curve-1 indicates that the molecular hydrogen ion is formed
D. Curve-2 represent the energy level of the antibonding region

Answer

b

Explanation

`BO of H_(2)^(2+) is (1)/(2)` hence curve `-2` shows bonding condition or decrease in potential energy.
