IMF's
The strongest type of IMF.
What is a hydrogen bond?
What VSEPR means.
What is Valence Shell Electron Pair Repulsion or electrons try to spread out as far as possible around the central atom?
When molecules have a high melting and boiling point, that means this about their IMF's.
What is they are strong?
The central atom must NOT have this to be linear.
What are lone pairs of electrons?
Tetrahedral shapes have this many legs.
What is 4?
The two different types of pair repulsion of VSEPR's.
What is lone electron pairs and bonded electron pairs?
Molecules do this to their IMF's to boil or melt.
What is break or overcome?
Dispersion forces are stronger in molecules with a molar mass that is this.
What is higher?
Bent shape bond angle.
What is about 105 degrees?
The process to determining if a molecule is polar.
What is whether the molecule is symmetrical or not?
INTERmolecular forces are weaker than these.
What are bonds or INTRAmolecular forces?
Dipole-dipole forces are seen in these types of molecules.
What is polar?
Water has this shape.
What is bent?
Methane (CH4) has this shape.
What is tetrahedral?
These traits of the central atom help to identify molecular shape.
What is number of bonds and lone pairs?
The 4 basic types of intermolecular forces.
What is (London) dispersion, dipole-dipole, hydrogen bond (not really a bond), and induced dipole?
A common gas used in photosynthesis with a linear shape.
What is CO2 (linear)?
Ammonia or NH3 has this shape.
What is trigonal pyramidal?
Definition of molecular polarity.
What is a separation of electric charge leading to a molecule having a dipole moment?
