For example, aqueous solutions of octahedral [Co(H2O)6]2+ are pink in colour but those of tetrahedral [CoCl4]2– are blue. The green colour of aqueous [Ni(H2O)6]2+ turns blue when ammonia is added to the solution to give [Ni(NH3)6]2+. The reduction of violet [Cr(H2O)6]3+ gives bright blue [Cr(H2O)6]2+. As with all colours, these arise from electronic transitions between levels whose spacing correspond to the wavelength available in visible light. The magnitude of spacing depends upon the factors such as the geometry of the complex, the nature of the ligands present, and the oxidation state of central atom. 62. Identify the complexes which is/are expected to be coloured? (A) [Ti(NO3)4] (B) [Cu(NCCH3)4]+ (C) [Cr(NH3)6]3+3Cl– (D) [Zn(H2O)6]2+ 63. Which of the following is -acid ligand?

Most of the amino acids are of left handed form, but with no reasons available. Even more interesting, recent experiments have shown that a 7–9% excess of four amino acids is present in Murchison meteorite discovered in 1970. This analysis shows life could arise outside the confines of earth. The origin of unequal distribution is probably because of electromagnetic radiations emitted in a corkscrew fashion from the poles of spinning neutron stars could lead to a bias of one mirror image isomer over another when molecules form in interstellar space. A stereogenic carbon can be defined as a carbon atom bearing groups of such nature that an interchange of any two groups will produce a stereoisomer. The device that is used for measuring the effect of optically active compounds on plane polarized light is a polarimeter. The analyser in the polarimeter decides the activity of compound present. This is being decided on the basis of angle by which axis of analyser has to be rotated for complete brightness. Left, right or no adjustment decides activity or optical inactivity respectively. 67. For existence of life, amino acids as ingredient of protein exist mainly in (A) form (B) d–form (C) Both (D) None of the above 68.

In one of the experiment performed by two students “Abraham” and “Fienkelstein” for measurement of optical activity of a substance. Result given by “Abraham” was: It is d–form with +30o rotation and by “Fienkelstein”, it was: It is form with –150o rotation. One of them can be correct only as solution can either be d form or, form. Which of the following is correct measure to come out of this dispute? (A) Result with acute angle is correct. (B) Result with obtuse angle is correct. (C) Students should perform another experiment by varying the concentrations or length of polarimeter tube to which angle of rotation is directly proportional. (D) Students should perform the experiment again with precaution. They will come on same conclusion as one of them must be committing observational mistake. COMPREHENSION - III Formation of amine salts can be used to isolate and characterize amines. Most amines containing more than six carbon atoms are relatively insoluble in water. In dilute aqueous acids, these amines form their corresponding ammonium salts and they dissolve. Formation of soluble salt is one of the characteristic functional group test for amines. The formation of amine salts is also used to separate amines from less basic compounds. When the solution is made alkaline (by addition of NaOH) the free amine is regenerated. The purified free amine either separates out of the aqueous solution or is extracted into an organic solvent. Many drugs and other biologically important amines are commonly stored and used as their salts. Amine salts are less prone to decomposition by oxidation and other reactions and they have virtually no fishy odor. The salts are soluble in water and they are easily converted to solution for syrup and injections. 72.

(A) Hoffmann bromamide reaction (B) Hoffmann elimination (C) Hoffmann rearrangement (D) None of these COMPREHENSION - IV Read the following paragraph and answer the questions given below: Triglycerides are the oils of plants and the fats of animal origin. They include such common substances as peanut oil, soya bean oil, corn oil, butter etc. Triglycerides that are liquid at room temperature are generally called oils; those that are solids are called fats. In simple triglycerides all three acyl groups are same and in mixed triglycerides acyl groups are different. Hydrolysis of oils and fats produces a mixture of fatty acids. Most natural fatty acids have unbranched chains and because they are synthesized from two carbon units, they have an even number of carbon atoms. In most unsaturated fatty acids double bonds are in cis configuration. Many naturally occurring fatty acids contain two or three double bonds. The fats or oils that these come from are called polyunsaturated fats or oils. The carbon chain of saturated fatty acids can adopt many conformations but tend to be fully extended because this minimizes steric repulsions between neighbouring methylene groups. Saturated fatty acids pack efficiently into crystals because of larger van der Waals’ forces these have high melting points. The cis configuration of the double bond of an unsaturated fatty acid puts a rigid bend in the carbon chain that interferes with crystal packing causing reduced van der Waals’ attraction between molecules. 77. The hydrolysis of fats or oils with NaOH is called (A) esterification (B) trans esterification (C) glycolysis (D) saponification 78.
