Carbohydrates contain C, H, and O. Hydrocarbons contain only C and H.

The typical general formula for a carbohydrate is CnH2mOm or Cn(H2O)m, where n3 and m can be different from n.

The name carbohydrate comes from the formula Cn(H2O)m (carbon + hydrate).

A typical carbohydrate is glucose, C6H12O6.

All the polar OH groups in carbohydrates tend to make them soluble in water.

Hydrocarbons are nonpolar and insoluble in water.
