2. (a) The v(CO) of isoelectronic series [Mn(CO),], [Cr(CO),] and [V(CO) are 2090 cm¹ 2000cm¹ and 1860 cm, respectively. Why is this difference observed in the band positions? (b) Account for the number of M-N and M-Cl stretching bands in cis-[Pd(NH3)₂Cl₂] and trans-[Pd(NH3)2Cl₂] complexes (c) Explain how terminal and bridging hydroxo complexes can be distinguished with the help of IR spectroscopy? (d) [Cr(OH)₂]3+ ions are pale blue-green but chromate (Cr₂O₂²) ion is an intense yellow in colour. Characterise the origins of the transition and explain.

Atomic Structure
The basic structure of an atom is defined as the component-level of atomic structure of an atom. Precisely speaking an atom consists of three major subatomic particles which are protons, neutrons, and electrons. Many theories have been stated for explaining the structure of an atom.
Shape of the D Orbital
Shapes of orbitals are an approximate representation of boundaries in space for finding electrons occupied in that respective orbital. D orbitals are known to have a clover leaf shape or dumbbell inside where electrons can be found.
