benzene


Benzene and toluene form nearly ideal solutions. At 20°C, the vapour pressure of benzene is 75 torr and that of toluene is 22 torr. The partial vapour pressure of benzene at 20°C for a solution containing 78g of benzene and 46 g of toluene in torr is (a) 50 (b) 25 (c) 37.5 (d) 53.5



To calculate the mass percentage of benzene and carbon tetrachloride in the given solution, we need to follow the steps given below: Step 1: Calculate the total mass of the solution. Total mass of the solution = mass of benzene + mass of carbon tetrachloride = 22g + 122g = 144g Step 2: Calculate the mass of each component in the solution.



To get this reaction, all you need to do is warm the benzenediazonium chloride solution. The diazonium ion reacts with the water in the solution and phenol is formed - either in solution or as a black oily liquid (depending on how much is formed). Nitrogen gas is evolved.



kobenhavn Answer: 0.16 Explanation: Empirical formula is the formula which gives the simplest ratio of the atoms of the elements contained in the substance. Molecular formula is the formula which gives the exact ratio of the atoms of the elements contained in the substance. Molecular formula of benzene is Empirical formula of benzene is



calculate the mole fracton of benzene ina solution containing 30% by mass of it in carbon tetrachloride Solution Let the total mass of the solution be 100 g and the mass of benzene be 30 g. ∴ Mass of carbon tetrachloride = (100 - 30)g = 70 g Molar mass of benzene (C6H6) = (6 × 12 + 6 × 1) g mol - 1 = 78 g mol - 1



Esample 2.6 The vapour pressure of pure benzene at a certain temperature is 0.850 bar. A non-volatile, non-electrolyte solid weighing 0.5 g when added b 39.0 g of benzene (molar mass 78 g mol−1 ). Vapour pressure of the soluthm then, is 0.845 bar. What is the molar mass of the solid substance?



Hint: Conversion of benzene to 4-bromonitrobenzene is a two-step process. Benzene converts to bromobenzene through a brominating catalyst. The brominated product is heated with mixed acid to get the required product. What is the Iupac name for C6H5Br? Bromobenzene | C6H5Br – PubChem. Which compound has an Iupac name of P-Bromonitrobenzene?



The vapour pressure of benzene at a certain temperature is 640 mm of Hg. A non-volatile and non-electrolyte solid weighing 2.175 g is added to 39.08 g of benzene. If the vapour pressure of the solution is 600 mm of Hg, what is the molecular weight of the solid substance? A 49.50 g/mol B 59.60 g/mol C 69.60 g/mol D 79.82 g/mol Hard Solution

gamma isomer of 1,2,3,4,5,6-benzene hexachloride Remarks ISO BSI common name in English­ speaking countries (recognized by ISO as synonym of )'-HCH) According to IUP AC rules the designation "benzene hexachloride" is incorrect. Nevertheless, it is still widely used, especially in the form of its abbreviation BHC.
