1) Why does methylbenzoate dissolve in concentrated sulfuric acid? 2) Give a detailed mechanism for the reaction (Be Specific) 3) Expalin in detail why you obtain meta substitution and not ortho or para substitution.? 4) What would you expect the structure of the dinitro product to be? Explain 5) You wish to obtain nitro toluene from benzene by carrying out an alkylation and a nitration. Is it important which order you carry out these reactions? Explain your asnwer.
A mysterious material was purified from safflower oil (hint: full of fatty acids). Upon ozonolysis it gave the following compounds in their respective molar ratios.
suppose a can contains gas at a pressure of 755 mm Hg and a temperature of 25 degrees celsius, what would be the pressure if the can was heated to 1155 degrees celsius ?
You may assume that delta H and delta S are independent of temperature.
A sample of gas has an initial volume of 3.0 L at a pressure of 747 mmHg,If the volume of the gas is increased to 3.4 L , what will the pressure be?
How many moles of Cr(OH)3 will dissolve in 1.00 L of a solution with a pH of 4.85. (Assume the pH does not change as the Cr(OH)3 is placed in the water.) (Ksp for Cr(OH)3 is 6.7 x 10-31)
