Question 1

hydrocarbons in which the atoms are

connected only by single bonds

Answer 1

Alkanes

Question 2

For the first 4 alkanes we use the

prefixes

Answer 2

• meth
• eth
• prop
• but

Question 3

They are colorless, have a characteristic odor and react with halogens in the presence of light, those with 1 to 10 carbons are more reactive

Answer 3

alkanes

Answer 4

alkanes

Question 5

uses: “wax” that are used to
coat fruits and vegetables to retain
moisture, Mineral oil.

Answer 5

alkanes

Question 6

unsaturated hydrocarbons that have at least one

carbon-carbon double bond
