Question 2

In a trigonal bipyramidal geometry, what is the bond angle between two atoms in the equatorial positions?

Accepted Answer

$$120^{\circ}$$

Question 3

A molecule has five electron domains: four bonding domains and one nonbonding domain. What is the molecular geometry of this molecule?

Accepted Answer

See-saw

Question 4

Which position does a nonbonding domain preferentially occupy in a trigonal bipyramidal structure, and why?

Accepted Answer

Equatorial, because it experiences less electron repulsion

A molecule has six electron domains: four bonding domains and two nonbonding domains. What is its molecular geometry?

Accepted Answer

Square planar

Question 10

Which of the following best explains why nonbonding domains occupy equatorial positions in a trigonal bipyramidal structure?

Accepted Answer

Equatorial positions have lower electron repulsion due to larger bond angles

Accepted Answer

Linear

Question 18

Which of the following best describes the difference between electron domain geometry and molecular geometry?

Accepted Answer

Electron domain geometry considers all electron domains, while molecular geometry considers only the positions of atoms
