Organic Chem

Question 1

Homologous Series

Answer 1

Is a series of organic compounds that have a similar chemical structure and chemical properties

Question 2

Organic Compounds

Answer 2

Compounds consisting of mostly carbon atoms most commonly covalently bonded to hydrogen, oxygen, nitrogen and phosphorous atoms.

Question 3

Hydrocarbons

Answer 3

Are molecules which only contain carbon and hydrogen atoms

Question 4

Functional groups

Answer 4

Are specific groups of atoms within a compound that affect the properties of the compound.

Question 5

Saturation

Answer 5

Alkanes - Are classified as saturated molecules since the carbon atoms are all bonded, with single bonds, to neighboring atoms.
Alkenes - Are classified as unsaturated molecules since the molecules contains at least one carbon to carbon double bond.

Question 6

Bromine water test

Answer 6

Bromine water which is orange, can be used to test for unsaturation. Alkenes, due to their carbon to carbon double bond, will decolorize the bromine water. Alkanes will not and so the orange colour of the bromine water remains.

Question 7

Cracking

Answer 7

Large hydrocarbon molecules can be broken down into smaller molecules using a catalyst. This is an example of a thermal decomposition reaction.
