A mixture containing 1-phenylethanol, benzoic acid and tert-butylbenzene were separated by column chromatography. Using neutral alumina as the stationary phase and ether as the eluent, the order in which these compounds leave the column is:



a.
tert-butylbenzene, 1-phenylethanol, benzoic acid

b.
benzoic acid, 1-phenylethanol, tert-butylbenzene

c.
1-phenylethanol, benzoic acid, tert-butylbenzene

why should we cool the contents of the conical flask before transferring them into a volumetric flask?

6. Blood plasma has a pH range of 7.35 - 7.45. From the midpoint of this range calculate the following:

a) [H3O+]

b) [OH-]

c) pOH

5.How many unique products would we have when 4 – ethyl – 1,2 – dimethylcyclopentane reacts with one equivalent of chlorine in the presence of light? Draw each of the following products.

Give iupac name. Br CH3 F
