The correct order in which the $O -O$ bond length increases in the following is
${H_2}{O_2} < {O_2} < {O_3}$
${O_2} < {H_2}{O_2} < {O_3}$
${O_2} < {O_3} < {H_2}{O_2}$
${O_3} < {H_2}{O_2} < {O_2}$
The number and type of bonds in $C_2^{2 - }$ ion in $CaC_2$ are
Which of the following best describes the diagram of molecular orbital?
The incorrect statement is :-
Use the molecular orbital energy level diagram to show that $\mathrm{N}_{2}$ would be expected to have a triple bond, $\mathrm{F}_{2}$ a single bond and $\mathrm{Ne}_{2}$ no bond.
In the molecular orbital diagram for the molecular ion, $N_2^ + $ , the number of electrons in the ${\sigma _{2p}}$ molecular orbital is
