Organics is not just “chemical free”. It is a whole systems or holistic means of growing and handling food. The whole system is linked – Soil. Plants.

So, there's been a reduction. Lithium aluminum hydride is one way to reduce a carboxylic acid. You could also accomplish this with borane, and borane is actually more chemoselective. We'll talk about that at the end of the video. For right now, let's focus in on the possible mechanism of lithium aluminum hydride reacting with our carboxylic acid.
