QUESTIONS FOR m-Dinitrobenzene lab (Nitration of the aromatic molecules)

1) what effect would the use of concentrated nitric acid in place of the fuming nitric acid have on the yield on m-dinitrobenzene? Explain Fully.

2) During the washing of the "crude" Product, the filtrate was checked with pH paper as it dripped from the funnel. Why was this done rather then check the filtrate that collected in the suction flask? Explain Fully.

3) give the name and formula of the principal organic impurity removed during the recrystallization of the dinitrobenzene. How can you account for the presence of this impurity?

4) Why was the recrystallized product air dried rather than dried over a suitable agent in a desiccator? Explain Fully.

5) Would it have been okay to use gravity filtration rather than suction filtration for the recrystallized product? WHY or WHY not?

6) Propose a mechanism for this reaction, clearly showing the electron flow and accounting for the observed product.

7) Explain why the meta product is formed and not the ortho or para.

The Photoelectric Effect Lab 10 Prelab Questions : Predictions If the light shining on the metal becomes brighter, will the kinetic energy of the emitted electrons increase? If the light shining on the metal becomes brighter, will the number of electrons being emitted per second (the photo-current) increase? If the frequency of the light shining on the metal is increased, will the number of electrons being emitted per second (the photo-current) increase? If the frequency of the light shining on...

What statistical test OR anova tests would you use for these questions? 1. As part of a marketing research project for a regional health advisory board, you have been asked to determine if any differences exist in the number of hours spent working out last year between employed and unemployed people. The variables to use in answering this question are FitnessHours (i.e. the total number of hours spent working out each year), and EmployStatus (i.e. employed, unemployed). Does the number...

In the Force lab, we use a small lab car with mass m=5 Kg, the experiment is on a horizontal table, on the car is acting a pulling force F= 20 N and the kinetic friction force Fr is acting as well. The car initially is at rest, and take 6.0 seconds to reach the velocity of 8.5 m/s. a) Calculate the magnitude of the friction force Fr acting on the car? b) We remove the pulling force when the...
