Draw the mechanism of Grignard Synthesis of Malachite Green. (Ensure that all mechanistic arrows are correctly drawn.) Show the following: - The gneration of the Grignard reagent followed by the reaction of that reagent with the ester. - The role of the HCl in the reaction (protonation of the alkoxide ion and reaction with excess Mg/Grignard reagent) - The subsequent dehydration of the tertiary alcohol to yield the final product (malachite green).
N2H4+3O2----2NO2+2H2O The limiting reagent is O2 how many kg of NO2 are produced from the reaction of 75kg of the limiting reagent.
what is the concentration of toluene in air produced by vaporizing 1 ml of liquid toluene into clean air to produce a total volume of 100 liters? Toluene has a molecular weight of 92
What mass in grams of tryptophan is in 0.25 quart of milk, assuming tryptophan accounts for 2.0% of milk by mass and that the density of milk is 1.04 kg/L.
What is the frequency factor, A? /(M · s) (C) Predict the value of the rate constant at 73°C. /(M · s)
The pKa of acetic acid, HC2H3O2, is 4.76. A buffer solution was made using an unspecified amount of acetic acid and 0.30 mol of NaC2H3O2 in enough water to make 1.50 L of solution. Its pH was measured as 4.50 on a meter.
How much heat is required to warm 215 g of ice from -44.1°C to 0.0°C, melt the ice, warm the water from 0.0°C to 100.0°C, boil the water, and heat the steam to 173.0°C?
a quantity of ice at 0.0 degrees Celsius was added to 33.6grams of water at 21.0 degrees Celsius to give water at 0.0 degrees Celsius. the heat of fusion of water is 6.01 kj/mol and the specific heat is 4.18 J/(g*celcuis) how much ice was added?
The protons that give rise to the signal at 7 ppm are more shielded than the protons that give rise to the signal at 9 ppm. B) The protons that give rise to the signal at 7 ppm are less shielded than the protons that give rise to the signal at 9 p..
A titration of sulfates in a 5.00 mL sample of drinking water with 10.0 mM (millimolar) of barium acetate as the titrant is carried out. A microflow pump was used instead of a buret
