This item has two statements. From the four options that follow, select the one that most accurately describes them. Statement 1: The ion [HeH]+ is more stable than H2+. Statement 2: The two species mentioned above have the same bond order.

1. Statement 1 is incorrect, while Statement 2 is correct.
2. Statement 1 is correct, Statement 2 is correct, and Statement 2 correctly explains Statement 1.
3. Statement 1 is correct, Statement 2 is correct, but Statement 2 does not explain Statement 1.
4. Statement 1 is correct, while Statement 2 is incorrect.

Correct answer: Statement 1 is correct, while Statement 2 is incorrect.

Solution

[HeH]+ is indeed more stable than H2+ due to its favorable bonding interactions, while the bond orders of the two species differ, making Statement 2 incorrect.
