Any molecule that contains only carbon, hydrogen, & oxygen atoms in a 1: 2: 1 ratio (e. g., c6h12o6) is a:

The answer to this is a carbohydrate compound. Carbohydrates have a general chemical formula of Cₓ(H₂O)ₓ. From the word itself, there is a ratio for every carbon atom that corresponds with the hydrate molecule or water. So, an empirical formula for a carbohydrate is CH₂O which coincides with the 1:2:1 ratio.

Ithink is a because if say increased in electronegativity

The answer is bhope this
