Question

This is an organic chemistry lab question.The experiment is on relative reactivities of some aromatic compounds. I'll give an overview of how what I did in the experiment and what i need help with. This might look like a lot but i really do need some help.

I used 0.070ml of Anisole + 0.5ml of Glacial acetic acid. I added 1.00ml of bromine/hydrobromic acid. the mixture was heated for about 15 minuted (a moistened sodium disulfide wool apparatus was attached to trap the escaping bromine).

Crystallization: Poured mixture into Erlenmeyer flask containing 5ml of water and 0.5ml of SATURATED BISULFIDE. It was suctioned to dry.

Recrystallization: I transferred the air dried solid into a flask and crystallized the brominated anisole using HEXANE. it was air dried and weight. Final weight of brominated anisole compound was 0.53g.

QUESTIONS... these are the questions from experiment that i need help with.

1) complete mechanisms including all intermediates and all charges, for ALL THREE REACTIONS based on the experimental product formed.

2) Theoretical yield of the product

3) actual yield (0.53g?)

4) Percent yield.

5) why did bromination take place at the position that id did in my final product?

My melting point range is 59.4-61.8. what does this say about my compound?

THANK YOU!.

Answer 1

In the bromination of Anisole the major product is p-bromoanisole and the minor product is o-bromoanisole What is the unit of melting point?

Post the remaining problema as new ones or try yourself

Hint:

1.Determine the masses of anisole and bromine.from volume and density

2.Determine the limiting reagent

3.Calculate the thoretical mass of p-bromoanisole

4 Calculate percent yirld
