Question

Which of the following options correctly describe the structure shown? Select all that apply.

1) The bond angles around C1 will be equal to 90°.
2) The overall geometry of this molecule is octahedral.
3) C₂ will have a linear geometry.
4) C1 will have a tetrahedral geometry.
5) The bond angles around C₂ are approximately equal to 180°.

Answer 1

The structure shown has a trigonal planar electron-pair and molecular geometry. The bond angles around C1 are approximately 120°, not 90° as mentioned in option 1.

Step-by-step explanation:

The structure shown can be described as having a trigonal planar electron-pair geometry and a trigonal planar molecular structure. The bond angles around C1 will be approximately equal to 120°, not 90° as mentioned in option 1. The overall geometry of the molecule is not octahedral (option 2) but rather trigonal planar. Option 3 is incorrect because C2 does not have a linear geometry. C1 does not have a tetrahedral geometry (option 4); it has a trigonal planar geometry. The bond angles around C2 are approximately equal to 120°, not 180° (option 5).
