Question 1

Define a hydrocarbon

Answer 1

An organic compound containing only carbon and hydrogen

Question 2

Define a Fraction

Answer 2

Hydrocarbons with similar boiling points separated from crude oil

Question 3

Define distillation

Answer 3

Separation of a liquid from a mixture by evaporation followed by condensation

Question 4

Define an alkane

Answer 4

Saturated hydrocarbon with a general formula of Cn2n+2

Question 5

Define saturated hydrocarbons

Answer 5

A hydrocarbon where all the carbon bonds are single bonds

Question 6

What is the definition of flammability

Answer 6

Easily ignited and capable of burning rapidly

Question 7

What is the definition of fractional distillation

Answer 7

Separation of many miscible liquids by heating at different boiling points in a fractioning column

Question 8

What is complete combustion

Answer 8

Combustion continued until no further with oxygen is possible for example the combustion of alkanes in oxygen to form CO2 and H20

Question 9

What is incomplete combustion

Answer 9

Burning of carbon based fuels in limited oxygen forming CO

Question 10

What is cracking?

Answer 10

Large hydrocarbons are broken down into smaller more useful molecules which can be used. Hydrocarbon vapour is passed over a catalyst and then it reacts

Question 11

What is an unsaturated hydrocarbon?

Answer 11

A hydrocarbon with one or more double or triple bonds

Question 12

What is an alkene

Answer 12

Unsaturated hydrocarbon which contains C = C bonds. General formula of CnH2n
