POGIL - IMF's

What is the difference between the formation of an ion and the formation of a momentary dipole?

• Ions form from transfer of electrons, momentary dipoles form from electrons being equally shared between two atoms and the electrons become unbalanced.

• Ions form from transfer of electrons, momentary dipoles form from electrons being unequally shared between two atoms and the electrons become unbalanced.

• Ions form from the sharing of electrons, momentary dipoles form from when a dipole exists in a covalent bond.

The difference in EN between hydrogen and bromine is 0.7, and the difference in EN between hydrogen and chlorine is 0.9. Which will experience stronger dipole-dipole interactions?

• HBr....HBr

• HCl...HCl

Neon has 10 electrons, and krypton has 18 electrons. Which element will have a greater chance of forming a momentary dipole?

• Neon because it has less electrons so is less polarizable

• krypton because it has more electrons and is more polarizable

Will neon with 10 electrons or krypton with 18 electrons

exhibit greater dispersion forces (LDF's)?

• neon because less electrons will will have less repelling so the atoms can attract more strongly

• Krypton because it has more electrons, so more temporary dipoles so more dispersion forces between the particles attracting them together.
