Question

the image shows a skeletal structure for a nanometer - sized molecular person, and an expanded version of the part of the structure corresponding to the head, with a carbon - oxygen - carbon bond angle indicated. based on what you know about valence shell electron pair repulsion theory (vsepr), what would you expect the c - o - c bond angle indicated to be? - 90° - 109° - 120° - 190° dont test me yet, i am trying to gain an understanding before attempting to answer this question. multiple choice 1 point

Explanation:

Step1: Identify electron - group geometry around O

The oxygen atom in the C - O - C bond has two bonding pairs and two lone pairs of electrons. According to VSEPR theory, the electron - group geometry around the oxygen atom is tetrahedral.

Step2: Determine bond angle

For a tetrahedral electron - group geometry, the ideal bond angle is 109°. But due to the repulsion between lone pairs (which are more repulsive than bonding pairs), the actual C - O - C bond angle is slightly less than 109°. However, among the given options, the closest value to the expected angle based on tetrahedral electron - group geometry is 109°.

Answer:

-109°
