Question: How do you determine which compound will have a higher boiling point?

How do you know which compound has a higher boiling point?

Compounds with stronger intermolecular forces, larger masses, and less branching will have higher boiling points. Compounds II and III only exhibit intermolecular London dispersion forces, so they would be the two lowest boiling compounds (weakest intermolecular forces).

Which of the following compounds will have the highest boiling point?

The hydrogen bond has stronger intermolecular forces. As branching increases boiling point decreases. Propan-1-ol has the highest boiling point because propan-1-ol contains H-bonding in their structure. Hence, Propan – 1 – ol has the highest boiling point amongst the given options.

How do you know which has the highest boiling point?

Consider the boiling points of increasingly larger hydrocarbons. More carbons means a greater surface area possible for hydrophobic interaction, and thus higher boiling points. As you would expect, the strength of intermolecular hydrogen bonding and dipole-dipole interactions is reflected in higher boiling points.

Which compound will have the highest boiling point quizlet?

The compound with the highest intermolecular forces will have the highest boiling point. Only choice C is capable of hydrogen bonding (having an O-H bond) and has the highest overall intermolecular forces and therefore the highest boiling pt.

Which of the following compound will have highest melting point?

p-Dichlorobenzene fits closely in the crystal lattice due to its symmetrical structure. Therefore, it has highest melting point.

How do you know which element has the highest melting point?

Melting Point

  • As the atomic number of elements increases, the melting point increases because there are more electrons around the nucleus, which creates a stronger negatively-charged force. …
  • Metals usually have high melting point due to ionic bonding between atoms. ( …
  • Non-metals usually have low melting points.

Which of these compounds will have the lowest boiling point?

The one with the weakest IMF will have the lowest boiling point. CH4 has only dispersion forces while all the others have dispersion PLUS either dipole-dipole (HCl, H2S, NH3), and/or hydrogen bonding (NH3). So, CH4 will have the lowest boiling point.
