Question

1-

The product of the nitration reaction will have a nitro group at which position with respect to the methyl group?

mostly para

mostly ortho

ortho and para at a 50:50 ratio

meta

2-

According to Sigma, what is the theoretical melting point of the para nitration product?

54 °C

243 °C

It decomposes at 300 °C

155 °C

3-

What is the MAIN safety concern with respect to how you handle waste for this lab?

Using acid/base indicators.

Don't know, usually pour it down the drain.

Labeling specific components of all the waste and putting them in separate waste containers.

Sulfuric acid and nitric acid oxidize acetone.

4-

What is the IUPAC name for this structure?

cyclohexanyl-4-methylpentane

isopentylcyclohexane

isohexylcyclohexane

(5-methylhexyl)cyclohexane

5-

How should you add the toluene to the mixture of nitric acid and sulfuric acid?

It doesn't matter.

Slowly.

All at once.

Slowly at first and then the rest all at once.

6-

What is the IUPAC name for this structure?

cyclononane

bicyclononane

cyclodecane

cyclopentylcyclohexane

7-

What is the drying agent (how are you removing water) in this lab?

saturated sodium chloride (brine)

calcium sulfate

magnesium sulfate

there is no water created during this experiment

Answer 1

Toluene reacts with concentrated Nitric acid and sulphuric acid forms Ortho-nitro toluene and para-nitro toluene due to methyl group present on benzene ring is Ortho, para directing group here Ortho-nitro toluene is major product than para-nitro toluene due to methyl group is toluene is not bulky group so, nitration easily takes place at Ortho position but not in para position
