Vocab
A compound formed when two or more atoms share electrons
What is Covalent compound?
Covalent compounds with no partial charges because the electrons are equally shared
What is nonpolar molecules?
the tendency for electron pairs to be as far apart as possible from one another
What is VSEPR?
A bonding pair
A lone pair
Multiple bonded pairs of e-
What constitutes as an electron domain?
If ΔEN = 0, it is nonpolar. Anything else is....
What is polar?
The bond between nonmetallic atoms that share electrons
What is Covalent bond?
Covalent compounds with partial charges in different locations within the overall neutral molecule
What is Polar molecules?
In H2O, the oxygen atom has a stronger attraction and pull on the electrons than the hydrogen atoms, and thus the oxygen side is a little more negative and the hydrogen side a little more positive, creating poles.
What is polar covalent?
This shape has 4 e- domains
What is Tetrahedral?
If symmetrical, it is nonpolar. If asymmetrical, it is...
What is polar?
A neutral group of atoms held together by covalent bonds
What is Molecule?
Formed in a molecule when equal and opposite charges are separated by a short distance
What is Dipole?
In O2, electrons are equally shared between the 2 atoms.
What is nonpolar covalent?
This shape has 2 e- domains
What is linear?
The strongest type of intermolecular forces.
What is hydrogen bonding?
When 2 atoms of the same element exist naturally as a molecule
What is Diatomic elements?
When a hydrogen atom bonded to a highly electronegative atom (like N, O, or F) is attracted to an unshared pair of e- on an electronegative atom in a nearby molecule.
What is Hydrogen bonding?
N2S
What is Dinitrogen monosulfide?
This shape has 8 e- domains. An example is SF6
What is Octahedral?
The weakest type of intermolecular forces.
What is London dispersion?
The space occupied by electrons
What is Electron domain?
An intermolecular attraction resulting from an instantaneous and temporary dipole created from the constant motion of electrons
What is London dispersion forces?
BBr3
What is Boron tribromide?
This shape has 4 e- domains.
(3 bonding pairs, 1 lone pair)
What is Trigonal pyramidal?
The stronger the intermolecular forces, the higher the _______________because it takes more energy to break apart the molecules held together in a liquid state.
What is boiling point?
