A) We often hear the terms organic, natural, and chemical in the media. Organic and natural are usually used to imply that a product is "healthy" and/or "environmentally friendly" while chemical often implies negative implications for health and for the environment. In your opinion, are these implications justified? Use specific examples to support your answer.
Note: I have no idea what they are asking me. I know that organic vegitables means that it was grown naturally, which means no use of artificial pesticides and GMOs (genetically modified organisms). I also know that organic chemistry is the study of hydrocarbons. I cant relate this 2 topic together. Plaese answer question A) and use a specific example.
B) Provide and briefly explain two examples of how organic chemistry can be used to improve existing products and thus provide solutions to newly identified health or environmental problems. (one example is unleaded instead of leaded gasoline. Think of 2 more)
Note: please also explain the example with leaded and unleaded fuel, how organic chemistry was used to make it better.
