Vedclass · Answer

(D) The potential energy $(P.E.)$ curve for a molecule depends on its bond order and bond dissociation energy.For $H_2$,the bond order is $1$ and it is a stable molecule with a deep potential energy well.For $H_2^+$,the bond order is $0.5$,making it less stable than $H_2$,so it has a shallower potential energy well compared to $H_2$.Looking at the provided graph,the curve labeled $a$ corresponds to $H_2$,$b$ corresponds to $H_2^+$,and $c$ corresponds to $H_2^-$.However,the graph shows $H_2$ at $a$,$H_2^+$ at $b$,and $H_2^-$ at $c$. The stability order is $H_2 > H_2^+ \approx H_2^-$. The graph correctly depicts the relative depths of the potential energy wells for these species. Therefore,all are correctly matched.

Which one of the following potential energy $(P.E.)$ graphs is not correctly matched?
