linear (2 ligands) (octa)

Question 16

PCl4 trick question is…

Answer 16

nonpolar it usually would be polar. The molecule has a positive charge due to the loss of an electron, but it is still nonpolar because of its symmetrical arrangement of atoms.

Becuasesymmetrical it is nonpolar

Question 17

Nonpolar has how many lone pairs…

Answer 17

none

Question 18

what is the exception of the octet rule?

Answer 18

6 and 5 ligands.

In the case of VSEPR 5 and 6 ligands, the central atom has more than eight electrons in its valence shell, which is an expanded octet. This is possible because the central atom has access to its d orbitals, which can accommodate additional electrons.

Question 19

what is intermolecular forces?

Answer 19

forces of attraction between molecules.

Question 20

What is intramolecular force?

Answer 20

forces that hold atoms together within a molecule.

Question 21

bonding electrons

Answer 21

electrons that bond to another electron.

Question 22

Name an element that form compounds that are an exception to the octet rule.

Answer 22

Hydrogen

Question 23

What is resonance?

Answer 23

When a molecule cannot be correctly drawn with just one Lewis structure.

Question 24

What bond is delocalized?

Answer 24

double bond.

Question 25

Identify the major assumption of the VSEPR theory that is used to predict the shape of molecules.

Answer 25

Electron pairs repel each other and try to get as far apart from each other as possible.

Question 26

In water, two hydrogen atoms are bonded to one oxygen atom. Why isn’t water a linear molecule?

Answer 26

Oxygen has two lone pairs which repel the bonds and makes a bent shape.

Question 27

How many lone pairs are in the Lewis structure for PCl3

Answer 27

10

Question 28

How many bonds are in the Lewis Structure for HCN

Answer 28

3
