Arrange the following reagents in INCREASING order of * nucleophilicity* in protic solvent: NaOCH, NaSCH, CH;OH CH,SH CH;CO,H Next arrange them in increasing order of nucleophilicity in aprotic solvent. Next arrange them in increasing order of basicity. Explain any differences between the different orderings.

I need solutions of Qa,b,d8. A student Ahmed was given five samples of simple salts labeled as A,B,C,D and E and he was asked to analyze systematically and report the acid and basic radical present in each. Answer the following questions based on the analysis.a. Write the name of any two preliminary tests that Ahmed has to definitely perform. b. Name a reagent which Ahmed can use to distinguish between a chloride, bromide and iodide ion containing salt. Explain the reactions involved between each halide ion and the reagent. c. Write any two safety measures he can follow while heating a solution in a test tube. d. The student observed that, addition of Barium chloride solution to an aqueous solutions of samples D and E produced a white precipitate. Write the possible reactions which leads to the formation of the precipitate. Identify the ions present in samples D and E based on the solubility of the precipitate in dilute HCl.

Following is a structural formula for guanidine, the compound by which migratory birds excrete excess metabolic nitrogen. The hydrochloride salt of this compound is a white crystalline powder, freely soluble in water and ethanol. Q. Does proton transfer to guanidine occur preferentially to one of its -NH2 groups (cation A) or to its =NH group (cation B)? Explain.
