Interpretation:
The positions of all double bonds in the given structure of caffeine are to be shown.
Concept introduction:
Covalent bonds are formed by sharing of electrons between atoms.
The valence electrons of Carbon are 4 electrons (requires 4 electrons to achieve octet).
The valence electrons of Oxygen are 6 electrons (requires 2 electrons to achieve octet).
The valence electrons of Hydrogen are 1 electron.
The sharing of one electron from two atoms constitutes a single bond between the two atoms. The sharing of two electrons from two atoms constitutes a double bond between the two atoms
