Polar And Non Polar Mol

Question 1

Do polyatomic molecules have dipole moments?

Answer 1

Yes, a dipole moment for each bond in the molecule. If do not cancel out- net dipole moment

Question 2

What is the ion dipole force equation?

Answer 2

U=-(Z+-mue e)/4 pi epsilon 0 r^2

Z= charge on ion (+1, +2)

Question 3

What is the strength of an ion dipole force compared to two charged particles?

Answer 3

Weaker- because of 1/r^2 dependance

Question 4

What is the arrangement of water molecules around an ion?

Answer 4

Inner circle- ion
Middle- primary hydrated sphere (4-8 water molecules tightly attracted to central ion)
Outer- outer hydration sphere
