Distillation

Question 1

How are the organic layer and aqueous layer identified in the separatory funnel

Answer 1

It goes by density. Heavier the compound= bottom layer
Less dense =top layer

Question 2

What factors affect the amount of compound extracted from the organic layer into the aqueous layer?

Answer 2

Salt can disrupt the aqueous layer by making it more polar. This decreases the solubility of the comping in the aqueous layer

Question 3

What is the purpose of distillation?

Answer 3

To purify a compound completely

Question 4

What is the advantage of using distillation to carry out a chemical reaction over simply heating a reaction mixture?

Answer 4

Distill decreases pressure & decreases bp preventing compound from decomposing before the vaporize.

Question 5

Thin layer chromatography purpose

Answer 5

is the separation of a mixture of two or more different compounds or ions by distribution between two phases, stationary and mobile

Question 6

Stationary phase

Answer 6

Is the silica gel on the plate

Question 7

Mobile phase

Answer 7

-is the solvent or mixture of solvents

Question 8

Process of stationary and mobile phase

Answer 8

Process of stationary and mobile phase
The distance that the spot is carried depends upon its polarity. The less polar the compound, the farther the spot will travel, and the greater the Rf value. More polar compounds travel shorter distances because they are more strongly attracted to, and more easily absorbed by the polar silica gel.

Question 9

What is the distance of a spot dependent on

Answer 9

Polarity

Question 10

The less polar the compound

Answer 10

The farther the spot will travel and the greater the Rf value

Question 11

Why do more polar compound travel shorter distances?

Answer 11

They are more strongly attracted to and easily absorbed by the polar silica gel
