# What is the angle between the carbon-oxygen bonds in the carbonate (CO_3^(2-)) ion?

Jun 30, 2017

$\angle O - C - O \equiv {120}^{\circ}$........
The central carbon atom is surrounded by $3 \times \sigma$ bonds, and a $C - O$ $\pi$ bond, that is conceived to be delocalized around the oxygen centres:
$O = C {\left(- O\right)}_{2}^{-}$
