Alkanes and Alkenes

Question 1

What are alkanes

Answer 1

Alkanes are a homologous series of hydrocarbons. This means that they have similar chemical properties to each other, and they have trends in their physical properties. For example, as the chain length increases, so does the boiling point. They are also saturated and less reactive than Alkenes.

Question 2

Alkane general formula

Answer 2

Cn H(2n+2) For example ethane (2) is C2H6

Question 3

What are Alkenes

Answer 3

Alkenes are a homologous series of hydrocarbons with a carbon double bond. They are unsaturated so they ae more reactive than alkanes

Question 4

Alkene general formula

Answer 4

Cn H2n for example ethene (2) is C2H4
