I am looking for question paper for chemistry subject of CBSE Board class 12th examination in PDF format ? Here I am giving you question paper for chemistry subject of CBSE Board class 12th examination (1) Why is ferric chloride preferred over potassium chloride in case of a cut leading to bleeding? 1 (2) Why does a tetrahedral complex of the type [MA2 B2] not show geometrical isomerism? 1 (3) How do you account for the miscibility of ethoxyethane with water. 1 (4) Give the IUPAC name of the organic compound 1 O II CH C CH C ) CH ( 3 2 3 − − = (5) Name the monomers of nylon 2 or nylon 6 ploymer. 1 (6) Give one example of an artificial sweetener used by the diabetic patients. 1 (7) Direct nitration of aniline is not carried out. Explain why? 1 (8) What type of linkage holds together the monomers of D.N.A.? 1 10. Analysis shows that a metal oxide has the empirical formula M0.96 O1.00. Calculate the percentage of M2+ and M3+ ions in this crystal? 2 OR In an ionic compound the anion (N¯) form cubic close type of packing. While the cation (M+) ions occupy one third of the tetrahedral voids. Deduce the empirical formula of the compound and the coordination number of (M+) ions. ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() Last edited by Neelurk; February 27th, 2020 at 10:34 AM. |
