Isomers with the same bond structure but the geometrical position of the atoms and functional groups differ are known … WebA very restrictive definition is as follows: Carbohydrates consist of carbon, hydrogen, and oxygen — with the hydrogen and oxygen occurring in a 2:1 ratio. There also must be at least three carbons. In other words, these are organic molecules that incorporate multiple water molecules and have at least three carbons.
