JEE CHEMISTRY MCQ: CHEMICAL BONDING & MOLECULAR STRUCTURE

Among ${O_2}^ + \,,\,{O_2}\,and\,{O_2}^ -$ the stability decreases as ${O_2}^ + > {O_2} > {O_2}^ -$

$H{e_2}$ molecule does not exist as the effect of bonding and anti-bonding orbitals cancel each other

${C_2},{O_2}^{2 - }\,and\,L{i_2}$ are diamagnetic

In ${F_2}$ molecule, the energy of $\sigma 2{P_z}$ is more than $\pi 2{P_x}\,and\,\pi 2{P_y}$
