Answer 2

• A comound made out of only hydrogen and carbon atoms

Question 3

What is an alkane?

Answer 3

• The simplest hysdrocarbon
• Each carbon atom makes 4 single covalant bonds
• Homologous series compounds
• Are saturated. This means that all carbons make 4 SINGLE covalant bonds

Question 4

What is the general forumla of an alkane?

Answer 4

• CnH2n+2

Question 5

What are the firs 4 hydrocarbons?

• Propane (C3H8)
• Butane (C4H10)

Question 6

What is are isomers?

Answer 6

• Two molecules made of the same atoms but the atoms are arranged differently
• Same molecular formula but different structural formula

Question 7

What does homologous series mean?

Answer 7

• All compounds in the group have similair properties so react in a similair way
• Compounds have the same functional group / same general formula
