Question

OH H2SO4 에 alachal How many grams of the above anhydride are needed to react with 5.0 g of cyclohexanol in the above reaction?

Answer 1

OH H₂SO4 TOH + ive H250 oor Molar mass of cyclohex and = 100.158 gimol, No. of moles = given mass molar mass 3 5.0 g cyclohex and = 5.0 g 100.158 ч clotox ano g/mol - 0.05 mole cyclohexanol. From the reaction stoichiometry we can say that 0.05 mole cyclohexanol will react with 0.05 mole anhydride

Molar mass of the anhydride = 120.14 gimot. mass of the anhydride in gm = no. of moles of anhydridex molar mass of the anhydride. 8 grams of anhydride needed = 0.05 mole x 1300 14 simos - 6.507 g
