The molecule contain only nonmetals.
covalent
Caffeine is a covalent compound. It is composed of carbon, hydrogen, and nitrogen atoms that form covalent bonds by sharing electrons.
Caffeine will typically bond with ionic bonds. It will not bond with covalent bonds because covalent bonds only bond with other metals.
Covalent bonds
Trimethylxanthine refers to caffeine, which is a covalent compound. It consists of carbon, hydrogen, and oxygen atoms bonded together through covalent bonds.
Caffeine is composed of carbon, hydrogen, nitrogen, and oxygen atoms bonded together by polar covalent bonds. This is because the atoms involved in the bonds have different electronegativities, causing an uneven distribution of electrons, which results in a polar molecule overall.
Covalent bonding can occur in solids, such as in diamond where each carbon atom forms covalent bonds with four other carbon atoms. However, in some solids, like metals and ionic compounds, the bonding is mainly metallic or ionic, respectively, due to the different types of interactions between atoms.
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.
In fact you can call caffeine both polar and nonpolar, as caffeine (or 1,3,7-trimethylxanthine) consist of both polar and nonpolar components.. On the internet I've seen a lot of people using caffeines ability to disolve in water as an argument for it to be polar.. This is not a good argument though, as caffeine in fact disolves in oils too due to the nonpolarity which I mentioned..
Hey i have a question do you need to see a doctor?
No, rum does not have caffeine in it.
Caffeine free means that the product has "no" caffeine in it.
