Q. Why do you think Berzelius put forth the vital force theory?

1. He wanted to prove that organic compounds cannot be synthesised in the lab.
2. He wanted to create a model to account for the observations of his time.
3. He knew it was just a theory, so it was bound to be false.
4. None of these.
