Bonding and Intermolecular Forces

Question 1

What is the equation for formal charge?

Answer 1

Vance electron - (1/2 bonding electron) - free electron

Question 2

What is the orbital geometry of H20

Answer 2

sp3 because of the lone pairs on oxygen

Question 3

Is a molecular polar or non polar when its electronegativity is equal to 0?

Answer 3

Non-polar

Question 4

Is a molecular polar or non polar when its electronegativity is greater than 0?

Answer 4

Polar

Question 5

How are ionic bonds formed?

Answer 5

They are formed by atoms with opposite charges (cations and anions)

Question 6

How are covalent bonds formed?

Answer 6

They are formed between atoms with high electronegativity (nonmetals and nonmetals)

Question 7

Are compounds with covalent bonds insulators and compounds with ionic bonds conductors?

Answer 7

Yes

Question 8

How are metallic bonds formed?

Answer 8

They are formed between atoms with low electronegativity (metals with metals)

“sea of electrons”

Question 9

How are coordinate covalent bonds formed?

Answer 9

They are formed between atoms with lone pairs and electron deficient species

Only one partner donates an electron so they are weak and can be taken apart easily

Question 10

What is a chelate?

Answer 10

It is a ligand that donates multiple lone pairs in a coordinate covalent bonds
