I looked at the structure and it has two Carbonyl groups, C=O, so perhaps that oxygen can hydrogen bond with hydrogen on water, It also has three methyl groups, CH3, which are nonpolar, so I do not know how soluble caffeine is in water, but it surely is in coffee which is mostly water.
Yes - caffeine is an organic molecule with a bunch of covalent bonds (aka molecular bonds).
Hydrogen form a covalent bond with carbon.
Hydrogen Bond
No. Hydrogen and oxygen bond covalently.

Covalent bond
Hydrogen can form one bond.
No. A hydrogen bond isn't even an actual bond. It is a form of intermolecular attraction.
A hydrogen bond is a very strong dipole-dipole bond. A hydrogen bond can only form between hydrogen and a strong electromagnetic atom; fluorine, oxygen or chlorine.
A hydrogen bond--two between A and T and three between G and C.
Hydrogen can form only one covalent bond because hydrogen has only one electron.
According to the definition, to form a hydrogen bond, a bond with hydrogen and another element should have a higher value for electronegativity such as H-N, H-O and H-F. H-Cl does not meet with sufficient polarity to form a hydrogen bond.
