Question

Question 1

True or false:

If distilling a mixture composed of ethyl acetate and toluene, toluene is the compound that distills first

Question 1 options:

Question 2

Distillation is....

A)

a purification technique based on the solubilities of different compounds

B)

a purification technique based on the polarity of different compounds

C)

a purification technique based on the boiling points of different compounds

D)

a purification technique based on the paramagnetic properties of different compounds

Question 3

True or false:

The distillation performed in this experiment is an example of a simple distillation.

Question 4

A mixture composed of methanol (boiling point of 65 oC), diethyl ether (boiling point of 35 oC) and ethyl acetate (boiling point of 77 oC) is distilled.

At what order do the three compounds distill, starting from first to last?

A)

diethyl ether, methanol, ethyl acetate

B)

ethyl acetate, methanol, diethyl ether

C)

methanol, diethyl ether, ethyl acetate

D)

diethyl ether, ethyl acetate, methanol

Question 5

Distillation is a physical process and not a chemical reaction

Explanation / Answer

1. False, since toulene has boilng point 110° while ethyl acetate has 77°which distill first.

2. Option C, it is based on boiling point

3. True since boiling point difference is more

4. Option A, since ether has less boiling point hence starts first to boil

5. True, it is physical process.
