What is electron pair repulsion theory
Lone pair repel a lot more because they are all negative

What does a line in flying wedge notation mean
In the plane to the paper
19 of 32
What does a solid wedge in flying wedge notation mean
Coming out of the paper towards you
20 of 32
What does a dotted wedge in flying wedge notation mean
Coming out behind the paper
21 of 32
What is a polar bond
A covalent bond where a difference in electronegativity causes a shift in electron density in the bond
22 of 32
What is a permeamant dipole dipole interaction
Intermolecular forces that exist because the difference in electronegativities in a polar bond causes weak electrostatic forces of attraction between molecules
23 of 32
What is induced dipole dipole interactions
A type of intermolecular force caused by temporary dipoles which causes all atoms & molecules to be attracted to each other
24 of 32
What is bond enthalpy
The energy required to break a bond between two atoms
