THE MCAT-CHEM 9
BONDING
| Question | Answer |
|---|---|
| What is electrostatic energy? | q1*q2 / r --> electrostatic potential * charge |
| What are strong ionic bonds created from? | high q values and small r values |
| What does it mean to have high charge density for ions that form strong ionic bonds? | charge : size ratio is high |
| How is an ionic bond formed? | electrons transfer completely from one atom to another resulting in an electrostatic interaction |
| lattice energy | energy required to break ionic bond |
| What is electrostatic force also called? | -Coulomb's Law -F = kq1q2 / r^2 |
| If r halves in the electrostatic force equation, what happens to electrostatic force? | increases by a factor of 4 |
| How are Coulomb's law and gravitation law related? | Gravitation force is tiny compared to electrostatic force |
| What is Coulomb's constant, k? | k = 9E9 |
| How to make hybrid orbitals? | hybridizing electron orbitals to produce certain geometries that facilitate bonding |
| What is an sp3 orbital made of? | hybrid between 1s and 3p orbitals |
| How is boron an exception to octet rule? | forms 3 bonds with 0 lone pairs |
| What does dipole moment depend on? | electronegativity difference and distance separating charges |
| Things with dipole moment are also known to be polar / nonpolar? | polar |
| lewis acids vs. lewis bases | -lewis bases donate electron pair -lewis acids accept electron pair |
| What are most covalent bonds made of? | nonmetals |
| What creates the most ionic bond? | greatest difference in electronegativity |
| create bonds = break bonds = | -release energy -take in energy |
