Answer 3

Saturated hydrocarbons contain only single covalent bonds while unsaturated hydrocarbons contain at least one or more double or triple carbon-carbon bonds.

Question 4

What are the properties of alkanes and alkenes?

Answer 4

Alkanes are compounds containing carbon and hydrogen with only single bonds.

Alkenes are compounds containing 2 or more double bonds.

Question 5
