The following graph is given, between total energy and distance between the two nuclei for species  $H_2^{+},H_2,H{e}_2^{+}\&H{e}_2$. Which of the following statements is/are correct?

$H_2^{ }$  is less stable than  $H{e}_2^{+}$

Bond dissociation energy of $H_2^{+}$   is more than bond dissociation energy of  $H{e}_2^{+}$.

Since bond orders of  $H{e}_2^{+}$ and  $H_2^{+}$ are equal both will have equal bond dissociation energy.

Bond length of  $H_2^{+}$  is less than bond length of $H_2^{ }$  .
