Question 1

Polymerization

Answer 1

Small unsaturated hydrocarbon chains (monomers) form long saturated hydrocarbon chains called a polymer

The one that has an n multiplied by it

Question 2

Saponification

Answer 2

Creates a soap that has both nonpolar chains (to clean non polar solutes) and ionic portion (to clean ionic and polar solutes

C3H5(C17H35COO)3 + 3NaOH –> 3C17H35COONa + C3H5(OH)3

Soap molecule has a head and tail

Fat and strong base forms soap and glycerin

Question 3

Substitution

Answer 3

A halogen reacts with a saturated hydrocarbon

Halogens: Any group 17 atoms

Saturated hydrocarbons: When the carbon atoms in the molecule are bonded to the maximum number of hydrogen atoms (examples: CH4, C2H6, C4H10)

Saturated hydrocarbons always are alkanes

Question 4

Esterification

Answer 4

Alcohol + Acid –> Ester + Water

Creates a great smelling organic compound

Always has water as a product but does not have water AND CO2 like Combustion does

Question 5

Combustion

Answer 5

Hydrocarbon + Oxygen –> Carbon Dioxide + Water
example: CH4 + 2O2 –> CO2 + 2H2O

Can be remembered because the two products are always carbon dioxide and water

Question 6

Fermentation

Answer 6

Sugar breaks down into alcohol and carbon dioxide in the presence of an enzyme

C6H12O6 –> 2CH3CH2OH + 2CO2

Reactant is always sugar (C6H12O6)

Product is always alcohol and carbon dioxide

Question 7

Addition

Answer 7

A halogen reacts with an unsaturated hydrocarbon

Halogens: Any group 17 atoms

Unsaturated hydrocarbons: When the carbon atoms in the molecule are not bonded to the maximum number of hydrogen atoms (examples: CH4, C2H6, C4H10)

They are alkenes and Alkynes
