(a) The equilibrium bond length of all AB' species will be shorter, and that of all AB species will be longer than that of the corresponding AB species. (b) The equilibrium bond length of all AB species will be shorter, and that of all AB" species will be longer than that of the corresponding AB species. (c) The equilibrium bond length of 0:. Ch'. CN ions will be shorter, than the corresponding neutral species. The equilibrium bond length of N2". NO" and Cl ions will be longer than the coresponding neutral species. (d) The equilibrium bond length of O,'. Clh, CN ions will be longer, than the corresponding neutral species. The equilibrium bond length of N:'. NO and Ch ions will be shorter than the corresponding neutral species. 3
