Question

The bond angle for the C-S-C bonds in the following molecule would be expected to be approximately: 
A)90 $\circ$ 
B)109 $\circ$ 
C)120 $\circ$ 
D)145 $\circ$ 
E)180 $\circ$

Quizplus · Accepted Answer

The C-S-C bond angle in this molecule is expected to be approximately 120 degrees. This is because the molecule has a trigonal planar molecular geometry around the S atom, with three bonding pairs and no lone pairs. In a trigonal planar geometry, the bond angle between the bonded atoms is 120 degrees. Therefore, choice C is the best answer.
