Question

What is the molecular geometry of the atoms bonded to the carbon atom indicated with arrow I in this structure of caffeine?

Answer 1

Trigonal planar

Step-by-step explanation:

If we look at the carbon atom indicated I in the image, we will discover that it is a carbon atom that is bonded to a nitrogen atom via a double bond.

Recall that an sp2 hybridized carbon atom has a trigonal planar geometry. When a carbon atom is sp2 hybridized, it is in a trigonal planar geometry as we can clearly see from the image.
