13. CH3(CH2)11Br 14. ZnCl2

B. Arrange all formulas in Hill Order.

Hill notation is a standard way of writing the formula for any chemical compound.

The empirical formula for any compound is written in correct Hill notation.

1. (H3C)3CC(CH3)3

First, Count All Carbon Atoms and record. C8

Second, Count all Hydrogen atoms and record: C18H18

Third, determine all other elements in compound. Count each and record in alphabetical order. C8H18

2. F2C6H3COCH3

First, Count All Carbon Atoms and record. C8

Second, Count all Hydrogen atoms and record: C8H6

Third, determine all other elements in compound. Count each and record in alphabetical order. C8H6F2

3. (CH3)2C=C(CH3)2

First, Count All Carbon Atoms and record. C6

Second, Count all Hydrogen atoms and record: C8H8

Third, determine all other elements in compound. Count each and record in alphabetical order. C8H8

4. C2H5COCH2CO2C2H5

First, Count All Carbon Atoms and record. C7

Second, Count all Hydrogen atoms and record: C8H12

Third, determine all other elements in compound. Count each and record in alphabetical order. C8H12O3

5. (FC6H4)2CO

First, Count All Carbon Atoms and record. C13

Second, Count all Hydrogen atoms and record: C8H8

Third, determine all other elements in compound. Count each and record in alphabetical order. C8H8F2O

6. NaHCO3

First, Count All Carbon Atoms and record. C1

Second, Count all Hydrogen atoms and record: C1H1

Third, determine all other elements in compound. Count each and record in alphabetical order. C1H1O3Na

Similarly do for others.
