1. (a) Reacting Pt2+ with two equivalents of each of the ligands NO2- and en, it is possible to prepare several complexes that could be described as both geometric and optical isomers of each other. Explain.
(b) What other type of isomerism might one envisage arising from the reaction given in (a)? 2. The aquated Cr2+ ion is sky blue in colour. If you were to obtain its UV-VIS spectrum, in what wavelength range will you expect this complex to absorb? Explain your reasoning. 3. (a) Determine the crystal field stabilization energy (CFSE) for the high and low spin complexes of an octahedral Co2+ metal complex. Make sure to include with your answer the energy for electron pairing as well.
(b) Identify which spin state is preferred based solely on the CFSE's. (c) Explain why though there is a preference for one over the other both cases are still possible.

Draw a reaction scheme with line-bond structures that illustrates how two amino acids combine to form a dipeptide. What conformation does the peptide bond usually adopt?
When an electron jumps from lower to higher orbit, its energy : (1) Increases (2) Decreases (3) Remains the same (4) None of these Ans: Increases
Q. What do you mean by Nuclear Fusion? Ans. The idea of fusion is that two small unstable nuclei are smooshed together to make one larger stable nucleus. This is the type
Enthalpy, H, is defined by the relationship H=U+pV. The enthalpy change, ΔH, for finite changes at constant pressure is given by the expression ΔH = ΔU+pΔV, so making the enthalpy
