Final answer:
There are three electron pairs shared between carbon 2 and 3 in the figure.
Step-by-step explanation:
The figure represents a carbon atom bonded with three oxygen atoms in a triangular shape.
The question asks about the electron pairs shared between carbon 2 and 3. In the given figure, there is a double bond (sharing of two electron pairs) between carbon 2 and oxygen 1, and a single bond (sharing of one electron pair) between carbon 2 and oxygen 2.
Therefore, there are three electron pairs shared between carbon 2 and 3.
