__________ 8. What is the force of attraction in Al ?
__________ 9. What is the strongest intermolecular force of attraction between water molecules?
Explanation / Answer
5. What is the strongest intermolecular force of attraction between CO2 molecules?
CO2 is non polar molecule
So, force of interaction in CO2 is London Forces
Answer: E
6. What is the strongest intermolecular force of attraction between PH3 molecules?
P has 1 lone pair on it. So, PH3 is polar in nature
The force of interaction here is Dipole-dipole forces
Answer: C
7. What is the force of attraction in CaO ?
CaO is compound formed by Ca2+ and O2-
The force of attraction here is ionic
Answer: A
8. What is the force of attraction in Al ?
Al is a metal. It has metallic bonding
Answer: D
9. What is the strongest intermolecular force of attraction between water molecules?
H2O forms hydrogen bonding which is strongest force here
Answer: B
