Which one of the following molecules is paramagnetic?
$N_2$
$NO$
$CO$
$O_3$
How many molecular orbitals filled with one or more electrons present in $N_2^+$ ?
Which molecule has the highest bond order
In the molecular orbital diagram for the molecular ion, $N_2^ + $ , the number of electrons in the ${\sigma _{2p}}$ molecular orbital is
The linear combination of atomic orbitals to form molecular orbitals takes place only when the combining atomic orbitals
$A$. have the same energy
$B$. have the minimum overlap
$C$. have same symmetry about the molecular axis
$D$. have different symmetry about the molecular axis
Choose the most appropriate from the options given below:
Compare the relative stability of the following species and indicate the magnetic properties : ${{\rm{O}}_2}{\rm{,O}}_2^ + ,{\rm{O}}_2^ - $ (super oxide); ${\rm{O}}_2^{2 - }$ (Peroxide)
