Topic 10: Molecular Geometry, Video F: Determining Molecular Geometry

Question 1

Trigonal bipyramidal with 3 lone pairs gives you what shape?

Answer 1

Linear

Question 2

Octahedral with 0 lone pairs produces what?

Answer 2

Octahedral.

Question 3

Trigonal bypramidal with 1 lone pair is called what?

Answer 3

See-Saw

Question 4

Trigonal planar with 1 lone pair is called what?

Answer 4

Bent

Question 5

What are the two components to VSEPR theory?

Answer 5

Electron geometry: apply the VSEPR rules for bonds and lone pairs to find 1st shape. Molecular geometry: Consider only the bonded atoms to find the second shape (count the number of lone pairs)

Question 6

Tetrahedral with one lone pair is called what?

Answer 6

Trigonal pyramidal with 107 degrees between bonds.

Question 7

Two lone pairs with a tetradhedral shaped atom is called what?

Answer 7

Bent with 104.5 degrees between bonds.

Question 8

Lone pairs do what to bond angles?

Answer 8

Distort the angles making them smaller.

Answer 9

The same.
