structure 2.2.6 - Molecular Polarity

Question 1

what does the molecule polarity depend on

Answer 1

the polarity of the bond and the geometry of the molecule

Question 2

Note: if a molecule contains all non polar bonds, irrespective of shape

Question 3

note: dipoles only ever cancel out for 3 shapes and when the bonds in the molecule are equal but opp

Question 4

what happens when dipoles “cancel”

Answer 4

the resulting molecule is non-polar

Question 5

what happens if dipoles are present and do not “cancel”

Answer 5

molecule is polar

Question 6

What does understanding the molecule polarity allow us

Answer 6

1. solubility
2. intermolecular forces
3. boiling + melting points

Question 7

What determines the molecule polarity of a structure

Answer 7

Lone pairs and bond polarity
