Among the following molecules/ions, `C_(2)^(2-), N_(2)^(2-), O_(2)^(2-), O_(2)`
Which one is diamagnetic and has the shortest bond length?

Highest bond order among the following molecules C_(2) , N_(2), O_(2), F_(2) is for

Arrange the following in the increasing order of bond length : O_(2),O_(2)^(-), O_(2)^(+)

Which of the following statements are correct ? (i) Amongs O_(2),O_(2)^(+),O_(2)^(-) and O_(2)^(2-),O_(2)^(+) has the greatest stability. (ii) Double bond in C_(2) consists of both Pi (pi) bonds because of the presence of four electrons in two pi molecule orbitals. (iii) Amongst B_(2),C_(2),N_(2) and O_(2) , mixing of 2s-2p orbitals takes palace only in N_(2) molecule. (iv) Isoelectronic molecules and ions have identical bond order.

Which out of O_(2)^(-)and O_(2)^(2-) has higher bond order and why ?

Arrange the following in the correct order of bond length N_(2), O_(2) and Cl_(2)

State the bond order and indicate whether the species is paramagnetic (i) B_(2) (ii) C_(2) (iii) N_(2) (iv) O_(2) (v) Br_(2) (vi) CI_(2)^(o+) Which of the following molecules has the highest bond order (i) Ne_(2) (ii) F_(2) (c) Explain why N_(2) has a greater dissociation energy than N_(2)^(o+) , whereas O_(2) has a lower dissociation energy tnan O_(2)^(o+) (b) The bonding sigma 2s orbital has a higher energy than the antibonding sigma^(**) 1s orbitals Why is the former a bonding orbital while the latter is an antibonding .
