Indicate FALSE and TRUE statements. Explain briefly your each answer.
………Bond energy of N2 is larger than that of O2.
……… 24Cr and 29Cu have the electron configurations 3d44s2 and 3d94s2.
………The symmetry species for doubly and triply degenerate representations are designated as A and B.
………NCl5 is a stable molecule but PCl5 is not stable.
………The point group of GeCl4 is Oh.
………The ionization energies of the group II A metals are in the order Ba>Sr>Ca>Mg.
………The radius increases as nuclear charge increases for ions with the same electronic structure such as O2-, F-, Na+, Mg2+.
(c) An octahedral cluster molecule E6 in Oh point symmetry can be formed without a central
atom and is bonded together using the six s and eighteen p orbitals on the six atoms. Each
vertex comprises a sp hybrid orbital (radial) pointing into the cluster, and two p orbitals
(tangential) at right angles to each other and to the centre of the cluster (see figure below).
These are the same as the ligand orbitals used in o- and x-bonding in octahedral transition
metal complexes. The bonding overlaps between these orbitals are shown below in A, B
and C, and two of these are each part of a triply degenerate set and the other is singly
degenerate - remember in O₂ symmetry x, y and z are degenerate.
