Q: What contains carbon, hydrogen, and oxygen in a ratio of 1:2:1?


Read this paragraph and choose the correct option from the provided answers:

The term carbohydrate comes from the fact that the majority contain carbon, hydrogen, and oxygen in a ratio of 1:2:1, making for an empirical formula of CH 2 O. This is somewhat misleading because the molecules are not actually hydrates of carbon at all. Carbohydrates are monomers and polymers of aldehydes and ketones that have multiple hydroxyl groups attached.

 Choices:

- helium

- sodium

- magnesium

- carbohydrate


A:
carbohydrate
