Re: RPMT Chemistry Paper
As you want the previous year question paper of chemistry of Rajasthan Pre Medical Test (RPMT) exam so here I am providing you. RPMT exam question paper Which one of the following is the correct statement? i. Chlorides of both beryllium and aluminium have bridged chloride structures in solid phase. ii. B2H6.2NH3 is known as 'inorganic benzene'. iii. Boric acid is a protonic acid. iv. Beryllium exhibits coordination number of six. The pKa of a weak acid, HA is 4.80. The pKb of a weak base, BOH, is 4.78. The pH of an aqueous solution of the corresponding salt, BA, will be i. 7.01 ii. 9.22 iii. 9.58 iv. 4.79 Amount of oxalic acid present in a solution can be determined by its titration with KMnO4solution in the presence of H2SO4. The titration gives unsatisfactory result when carried out in the presence of HCl, because HCl i. reduces permanganate to Mn2+. ii. oxidises oxalic acid to carbon dioxide and water. iii. gets oxidised by oxalic acid to chlorine. iv. furnishes H+ ions in addition to those from oxalic acid. Sol: KMnO4can oxidise HCl along with oxalic acid into Cl2 and itself gets reduced to Mn2+. Among the following substituted silanes the one which will give rise to cross linked silicone polymer on hydrolysis is i. R2SiCl2 ii. R3SiCl iii. R4Si iv. RSiCl3 For more questions here is the attachment |
