4.8 Shapes of Molecules with 5 Or 6 Electron Domains

Question 1

What is the name of the shape of a molecule with a molecule with 5 total electron domains with 5 bonding pairs and what is the bond angle?

Answer 1

Trigonal bipyramidal 90 and 120 degrees.

Question 2

What is the name of the shape of a molecule with a molecule with 5 total electron domains with 4 bonding pairs and what is the bond angle?

Answer 2

See saw 88 and 118 degrees.

Question 3

What is the name of the shape of a molecule with a molecule with 5 total electron domains with 3 bonding pairs and what is the bond angle?

Answer 3

T shaped 88 degrees.

Question 4

What is the name of the shape of a molecule with a molecule with 5 total electron domains with 2 bonding pairs and what is the bond angle?

Answer 4

Linear 88 degrees.

Question 5

What is the name of the shape of a molecule with a molecule with 6 total electron domains with 6 bonding pairs and what is the bond angle?

Answer 5

Octahedral 90 degrees.

Question 6

What is the name of the shape of a molecule with a molecule with 6 total electron domains with 5 bonding pairs and what is the bond angle?

Answer 6

Square pyramidal 88 degrees.

Question 7

What is the name of the shape of a molecule with a molecule with 6 total electron domains with 4 bonding pairs and what is the bond angle?

Answer 7

Square planar 90 degrees.

Question 8

What is important about the axial and equatorial positions in a trigonal bypyramid?

Answer 8

They are not equivalent lone pairs always go in the equatorial position (around the middle). This rule only holds for five electron domains.
