Question

Explain why the following compounds have different boiling points: HCl (-85*C), HF(20*C), TiCl4(nonpolar,136*C), and CsCl(a salt,1290*C)

Answer 1

Answer 2

So for CsCl I said it's an ionic bond because EN>1.6 meaning greater polarization

Answer 5

Well, the CsCl is an ionic compound so it's going to have a high boiling point. TiCl4 that's non polar but it's molecular weight may play a factor in why it's BP is high. H-Cl well i think it's intermolecular forces are weak probably just a dipole dipole attraction. H-F has hydrogen bonding that accounts for why it's unusually higher than HCl
