Methylation of 10g of benzene gives 9.2g of toulene, the % yield is:

Methylation of 10g of benzene gave 9.2g of toluene. Calculate the percentage yield of toluene ______(Nearest integer)

Benzene and toluene form nearly ideal solutuions. At 20^(@)C , the vapour pressure of benzene is 75 torr and that of toulene is 22 torr. The partial vapour pressure of benzene at 20^(@)C for a solution containing 78g of benzene and 46g of toluene in torr is

In the above reaction, 3.9 g of benzene on nitration gives 4.92 g of nitrobenzene. The percentage yield of nitrobenzene in the above reaction is "_____________" %. (Round off to the Nearest Integer ). ( Given atomic mass : C : 12.0 u, H : 1.0 u, O : 16.0 u, N : 14.0 u )

Benzene and toulene form an ideal solution. 3 mole benzene and 2 mole toulene are added. V.P. of pure benzene and toulene are 300 & 200 mm of Hg respectively. The V.P of the solution (in mm of Hg) is

What is the mass percentage of carbon tetrachloride if 22 g of benzene is dissolved in 122 g of carbon tetrachloride ?

The dehydration yield of cyclohexanol to cyclohexene is 75% . What would be the yield if 100 g of cyclohexanol is dehydrated?

0.90g of a non-electolyte was dissolved in 87.9 g of benzene. This reised the boiling point of benzene by 0.25^(@)C . If the molecular mass of the non-electrolyte is 103.0 g mol^(-1) , calculate the molal elecation constant for benzene.

0.75 g of a non-electrolyte was dissolved in 87.9 g of benzene. This raised the boiling point of benzene by 0.25^(@)C . If the molecular mass of non-electrolyte is 103 , calculate the molal elevation constant for bezene.
