Intermolecular Forces
The IMF's from strongest to weakest are
Hydrogen Bonds, Dipole Interactions, and Dispersion Forces
A Trigonal Planer is polar
False
To fulfill the octet rule, nonmetal will bond by sharing
Electrons
The dipoles will point to the atom with this
The atom with the highest electronegativity
The four levels of polarity
Nonpolar, Moderately Polar, Very Polar, and Ionic
All compounds have this type of IMF
What are London Dispersion Forces?
Do single, double, and triple bonds affect the geometry of a molecule differently
No
The subatomic particle that affects geometry the most
Electrons
When a little delta is present in a molecule, there is a
Partial Charge
The most common polar molecule
What is H2O
A bond in which two molecules bond because of electric polaization
What is a Dipole Interaction?
Moleules that are bent or angular can have one or two lone pairs
True
Lone Pairs are
The valence electrons in an atom that are not used to bond
A molecule is nonpolar when this happens
The dipole movements cancel each other out
Is the molecule CH3Cl polar or nonpolar
Polar
Elements that help form hydrogen bonds
Molecules with these are asymmetrical
What are Lone Pairs?
The number of domains in a molecule is determined by
The number of bonds connected to the central atom
Dipoles are not present in this type of bond
What are Ionic Bonds
Moderately polar bonds tend to occur when the electronegativity difference this
0.0 to 0.4
Vander Waals forces determine this
What is the boiling and melting point?
The difference between a Tetrahedral and Trigonal Pyramid
A Trigonal Pyramid has a lone pair on its central atom. Making the Trigonal Pyramid polar. A Tetrahedral has no lone pairs and is nonpolar.
What is electron geometry
Electron geometry is the arrangement of electron density around the central atom.
Dipoles will show that a molecule is nonpolar if
They are of the same strength and are either all pointing towards or away from the central atom
Even when the electronegativity of atoms differ greatly, this can determine the overall polarity of a molecule
What is Symmetry?
