Question

Quizplus · Accepted Answer

The molecule COS has a central carbon atom with one oxygen and one sulfur atom bonded to it, and it also has a negative charge, indicating an extra electron. This gives the carbon atom a total of three regions of electron density (two single bonds and one lone pair), leading to a trigonal planar electron geometry and molecular geometry.
