Question

Consider the given figure showing the formation of $H_{2}^{+}$ ion depending on internuclear distance versus potential energy of the system.

which is correct statement:

• 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 represents the energy level of the antibonding region

Answer 1

Answer: (B)

Curve-2 represents the most stable state of the system for $H_{2}^{+}$ ion

Answer 2

BO of $H_{2}^{+}$ is $\frac{1}{2}$ hence curve –2 shows bonding condition or decrease in potential energy
