Quesiton 14

Of the solvents that we used in our TLC experiment, which is least polar?

Hint: When a non-polar and polar solvent are mixed, the polar solvent dominates in the overall polarity of the solvent.

Select one:

a. acetic acid

b. ethyl acetate

c. ethanol

d. hexanes

e. 1,2-dichloroethane

Question 15

The compounds that penetrate the human body best are ...

Select one:

a. the ones that are somewhat soluble in water but not grease.

b. the ones that are insoluble in both water and grease.

c. the ones that are insoluble in water but are somewhat soluble in grease.

d. the ones that are somewhat soluble in both water and grease.

Question 14: d. Hexane

Hexane is a carbon chain having 6 carbons and it is non-polar compound. So it is having least polarity.

Question 15: a. the ones that are somewhat soluble in water but not grease

water is present in Human body, So polar compounds are soluble in water and they can penetrate into human body.
