And you are right. They need to have orbital hybridisation. SP{,2,3}.
And in other meaning as produced by organism nearly all food is organic too. Some stuff like sugars should be possible to make without organisms(but you know it better than me), but too expensive compared to produced by organisms.
Sorry for awkward sentences, English is not my native language.
EDIT: there are apparently more meanings
When people use the word "organic" for food, they're specifically referring to particular certifications, like the National Organic Program in the USA, and foods that are "organically farmed". I agree that the naming isn't ideal, but the word "organic" is very commonly used for this, and therefore it's a legitimate definition of "organic". That's just how language works :)
Lucky you. It could have been derailed.
