Question

question 11 (1 point) the bond angle in co3 2- is expected to be approximately 90 degrees 109.5 degrees 120 degrees 145 degrees 180 degrees

Explanation:

The carbonate ion ($CO_3^{2 -}$) has a trigonal - planar geometry due to $sp^2$ hybridization of the central carbon atom. In a trigonal - planar geometry, the bond angles are approximately 120 degrees.

Answer:

C. 120 degrees
