The following exercise contains 7 questions. All of the questions are taken from the video you just watched.

Write the correct answer where necessary and chose between true or false in the last two.

The correct answers for the exercise :

1. unsaturated hydrocarbons

2. alkanes

3. alkynes

4. alkenes

5. before

6. false

7. false

Now you know the difference between alkanes, alkenes and alkynes. I hope you find it interesting and useful!

Thank you :)
