The IUPAC name of [Co(H_2NCH_2CH_2NH_2)_2 (NO_2)NO_5 is bis(enthane-1,2-diamine) dinitrito-N-cobalt(III) nitrate.It follows the following rules that. (a)Cation is named first followed by anion. (b) Ligands are named in an alphabetical order before the name of the central atom/ion. ( c)Name of anionic ligands end in "o" (ex.chlorido) those of neutral (and if cation) ligands are the same except aqua for H_2O , ammine for NH_3 etc. (d)Prefixes mono,di,tri,etc.are used to indicate the number of individual ligand.When the name of the ligands include a numerical prefix, then terms bis, tris, tetrakis are used. (e)Oxidation state of the metal is indicated by Roman numeral in parenthesis. (f) For cationic and neutral complexes, the metal is named same as the element and for anionic complex, the name of metal ends with suffix-ate.For some metals, the Latin names are used in the complex anions , e.g., ferrate for Fe, argentate for silver etc. The correct IUPAC name of the coordination compound [Pt(NH_3)_2Cl(NH_2CH_3)] is :

In an experiment to estimate the size of a molecule of oleic acid 1 mL of oleic acid is dissolved in 19 mL of alcohol. Then 1 mL of this solution is diluted to 20 mL by adding alcohol. Now, 1 drop of this diluted solution is placed on water in a shallow trough. The solution spreads over the surface of water forming one molecule thick layer. Now, lycopodium powder is sprinkled evenly over the film and its diameter is measured. Knowing the volume of the drop and area of the film we can calculate the thickness of the film which will give us the size of oleic acid molecule. Read the passage carefully and answer the following questions (a) Why do we dissolve oleic acid in alcohol ? (b) What is the role of lycopodium powder? (c) What would be the volume of oleic acid in each mL of solution prepared? (d) How will you calculate the volume of n drops of this solution of oleic acid ? (e) What will be the volume of oleic acid in one drop of this solution ?
