What molecular geometry is associated with an AB₂ compound?
What molecular geometry is associated with an AB₃ compound?
What molecular geometry is associated with an AB₄ compound?
What molecular geometry is associated with an AB₂E compound?
What molecular geometry is associated with an AB₃E compound?
What molecular geometry is associated with an AB₂E₂ compound?
How many lone pairs does a bent molecule have?
1 (or 2, if it has 2 it will make the bond angles smaller)
What are the subtypes for covalent compounds?
1. diatomic molecule
2. binary acid
3. binary molecular
What is the central atom?
* Carbon if present
* If carbon isn't present it is the least electronegative atom
Hydrogen + Carbonate
Hydrogen + nitrate
Hydrogen + nitrite
Hydrogen + sulfite
Hydrogen + sulfate
If you're naming a binary acid, what are the rules for naming?
Use example: HF
Take the prefix of hydrogen (Hydro) and the first syllable of the anion (Fluor) and add the suffix "ic"
Answer: Hydrofluoric acid
If you're naming an oxyacid, what are the rules for naming?
1. First check the ending of the polyatomic ion. If it ends in "ate" or if it ends in "ite." If it ends in "ate" your new ending will be "ic," if it ends in "ite," your new ending will be "ous"
2. Remove hydrogen from the name, it isn't used in naming oxyacids.
3. remove ending from polyatomic ending and add the new ending.
H₂SO₄ (dihydrogen sulfate) -> Sulfuric Acid
HNO₂ (Hydrogen Nitrite) -> Nitrous Acid
A lattice structure is formed in what type of bond?
When is a polar bond formed?
When there is an unequal sharing of electrons, creating partial positive and negative charges
