97. It's cis-3-Hexenal

It's a short chain aldehyde with the double bond & carbonyl on the same isometric plane.
People are so sensitive to the odor that it takes under ¼th part per billion to detect it!
Early in career, I did a decent amount of work in flavors & fragrances.
You are spot on. The release of it is, indeed, part of the plant's defense mechanism.
There are other oxygen bearing compounds released, but this one is what we detect the best.
