Caffeine molecule with lone pairs
WebSteric Number=No. of sigma bonds + No. of lone pairs ....and then then the value of the steric number gives us the number of hybridized orbitals. Coming to the doubt about sigma and pi bonds, remember that the first bond between 2 atoms is always a sigma bond and any additional bond between these 2 atoms will be a pi bond. WebMay 7, 2024 · The nitrogen atoms in the caffeine molecule are all essentially planar. Even though some are often drawn with three single bonds, the lone pairs on these atoms are involved in resonance with adjacent double-bonded carbon atoms, and thus adopt an sp2 orbital hybridisation.
