Q51.The formula of a gaseous hydrocarbon which requires 6 times of its own volume of O2 for complete oxidation and produces 4 times its own volume of CO2 is CxHy. The value of y is ________. Q52. 1. 86 g of aniline completely reacts to form acetanilide. 10% of the product is lost during purification. Amount of acetanilide obtained after purification (in g) is ___________ ×10−2.
What This Question Tests
This question involves determining the molecular formula of a hydrocarbon by applying stoichiometry to its complete combustion reaction with oxygen and the volumes of products formed.
Concepts Tested
Formulas Used

Q93.Which of the following chemical reactions depicts the oxidizing behaviour of H2SO4 ? (1) 2HI + H2SO4 ⟶I2 + SO2 + 2H2O (2) Ca(OH)2 + H2SO4 ⟶CaSO4 + 2H2O (3) NaCl + H2SO4 ⟶NaHSO4 + HCl (4) 2PCl5 + H2SO4 ⟶2POCl3 + 2HCl + SO2Cl2
Q64.Amount of oxalic acid present in a solution can be determined by its titration with KMnO4 solution in the presence of H2SO4 . The titration gives unsatisfactory result when carried out in the presence of HCl , because HCl (1) gets oxidised by oxalic acid to chlorine (2) furnishes H+ ions in addition to those from oxalic acid (3) reduces permanganate to Mn2+ (4) oxidises oxalic acid to carbon dioxide and water
