The term, London forces, is a synonym for A) B) C) D) E) ion-ion forces permanent dipole-permanent dipole interactions hydrogen bonding instantaneous dipole-instantaneous dipole interactions instantaneous dipole-induced dipole interactions 10. Which one of the following molecules is most polarizable, and subject to significant instantaneous dipole-induced dipole forces? A) HC-Br B) HC-C C) HC-F

Explanation / Answer

Q6.

molecular crystals --> must be made up by molecules (i.e. covalent bonding)

a) KF = this is ionic

b) F2 = will not form crystals

c) this is ionic

d) SiOI3 --> will form cyrstals

e) Co --> metallic, will form metalic species
