Question

Based on the type or types of intermolecular forces, predict
the substance in each pair that has the higher boiling point: (d) phosgene (Cl2CO) or formaldehyde (H2CO)

Accepted Answer

Hey everyone, we're asked to identify the compound that has a higher boiling point between metal for me or formal chloride first, let's go ahead and draw this out. Now, looking at our two structures, we can see that we have disciple disciple interactions for both. And since we only have dipole dipole interactions for both, we have to compare their molecular masses in order to determine which one has a higher boiling point. And since formal chloride has the larger molecular mass, this means that it will have the higher boiling point. And another reason why our method format doesn't have a higher boiling point than our formal chloride is because it doesn't have the capacity to hydrogen bond and our hydrogen is not bound to a strongly electro negative element. So our final answer here is going to be formal chloride with the higher boiling point. So I hope that made sense. And let us know if you have any questions.
