There are 29 bonds in caffeine! How did I get my answer?
The chemical formula for caffeine is C8H10N4O2
1. Count total octet electrons
64+20+32+16=132
2. Count the # of valence electrons in the molecule.
32+10+20+12=74
3. Subtract valence electrons from octet electrons
132-74=58
4. Divide the bonding electrons by 2 to find the number of bonds.
58/2=29
Caffeine's formula is C8H10N4O2, therefore there are 8+10+4+2 = 24 atoms in each molecule of caffeine.
25 sigma bonds
Caffeine will typically bond with ionic bonds. It will not bond with covalent bonds because covalent bonds only bond with other metals.

Epinephrine or also known as adrenaline contains 6 pi bonds. Epinephrine is a naturally occurring hormone that is also commercially manufactured for use as heart stimulant.
According to edexcel mark scheme, caffeine has both London forces and permanent dipole forces.
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.
Caffeine has only one formula: C₈H₁₀N₄O₂ There are, however many, many, many different sources of caffeine; more than 60 plants are known to contain caffeine naturally including coffee beans, tea leaves, and kola nuts.
To answer your question on how many hydrogen atoms are there in caffeine, the scientific answer would be 10 atoms of hydrogen.
Caffeine is C8H10N4O2 and has 10 hydrogen atoms.
The answer is 5,15.1e-4.
