Question 6

General Formula

Answer 6

The trend/ratio of atoms in a homologous series

Question 7

Homologous series

Answer 7

A group of chemical with:
-The same general formula (only differing by the number of CH2 units)
-Show a trend in physical properties
-Similar chemical reactions

Question 8

Functional Group

Answer 8

Parts of an organic molecule that determines its reactions

Question 9

Isomer

Answer 9

Molecule that has the same molucular formula but different structure

Question 10

Compound prefixes

Answer 10

1. Meth-
2. Eth-
3. Prop-
4. But-
5. Pent-
6. Hex-

Question 11

Substitution

Answer 11

A hydrogen atom is replaced with another atom. UV light is needed to break the bond.

Question 12

Complete combustion

Answer 12

Hydrocarbon + Oxygen –> Carbon Dioxide + Water

Question 13

Incomplete Combustion

Answer 13

Hydrocarbon + Oxygen –> Carbon Monoxide + Water

or

Hydrocarbon + Oxygen –> Carbon + Water

Question 14

Addition

Answer 14

More atoms can be added because the compuound in unsaturated (contains a double bond).

Alkenes can undergo addition because they are unsaturated compounds.
