(d) The normal boiling point of Cl2 (l) (238 K) is higher than the normal boiling point of HCl(l) (188 K). Account for the difference in normal boiling points based on the types of intermolecular forces in the substances. ... larger than the intermolecular forces (London and dipole-dipole) among HCl molecules.
Does Cl2 have a higher boiling point than F2?
Larger size means there are more electrons available to form the dipoles. Cl is lower on the Table. It has 3 energy levels while F has only 2 energy levels. So Cl2 is larger than F2 .
Does KCl or Cl2 have a higher boiling point?
KCl has higher boiling point because KCl is an ionic compound with strong bonds that are hard to break and require more heat to break apart. Whereas Cl2 is a covalent compound and its bonds need lesser energy to break.
Which molecule has the highest boiling point?
Water in fact has the highest boiling point because although its individual hydrogen bonds are not as strong as hydrogen fluoride
Is Br2 stronger than F2?
Differences in boiling points between molecules are due to varying strength of intermolecular forces. From the data given, we know Br2 must have the strongest intermolecular forces as it has the highest boiling point, followed by NH3 and then F2.
What increases boiling point?
Compounds that can hydrogen bond will have higher boiling points than compounds that can only interact through London dispersion forces. An additional consideration for boiling points involves the vapor pressure and volatility of the compound. Typically, the more volatile a compound is, the lower its boiling point.
How do you know what has the highest boiling point?
Explanation: The order of strengths of intermolecular forces is: ion-ion > H-bonding > dipole-dipole > London dispersion
Which functional group has highest boiling point?
Carboxylic acids have higher boiling points than all other functional groups mentioned.
Why is Br2 stronger than F2?
Differences in boiling points between molecules are due to varying strength of intermolecular forces. From the data given, we know Br2 must have the strongest intermolecular forces as it has the highest boiling point, followed by NH3 and then F2.
Why does F2 have a low boiling point?
Bigger molecules will have stronger London dispersion forces
Why does F2 have such a low boiling point?
It is a simple covalent non polar molecule like oxygen, but Fluorine is smaller and has fewer elections. This causes it to have lower London forces
Does F2 have a low melting point?
The smallest (CH4) likely has the weakest intermolecular forces. Higher boiling points will correspond to stronger intermolecular forces. ... So I2 has the strongest forces, and F2 will have the weakest .
What determines boiling point?
Types of Molecules: the types of molecules that make up a liquid determine its boiling point. If the intermolecular forces between molecules are: relatively strong, the boiling point will be relatively high. relatively weak, the boiling point will be relatively low.
