Is cl2 or F2 less volatile?
Cl2 is less volatile because it has more intermolecular forces and therefore has a higher boiling point.
Is this right?
Yes, but you ought to think out what (at the same temperature), what the average KE does to heavier molecules...and that lessens the escape changes of the heavier molecule to break away from the surface.
Oh okay. We didn't learn that as of now. But I'll include that into my answer.
No, your statement is not accurate. Chlorine (Cl2) and fluorine (F2) are both highly volatile and have low boiling points. The difference in intermolecular forces between these two substances is not significant enough to determine which is less volatile. Both Cl2 and F2 exist as diatomic molecules and have temporary dipole-dipole interactions due to their nonpolar nature. Additionally, F2 has stronger London dispersion forces due to its larger atomic size, which may give it a slightly higher boiling point compared to Cl2. However, in general, both Cl2 and F2 can readily evaporate and have low boiling points, making them highly volatile substances.
Not quite. To determine which compound, Cl2 (chlorine gas) or F2 (fluorine gas), is less volatile, we need to consider their intermolecular forces and boiling points.
Both chlorine gas (Cl2) and fluorine gas (F2) are non-polar molecules, which means they only have London dispersion forces as their intermolecular forces. London dispersion forces are the weakest intermolecular forces and occur due to temporary fluctuations in electron density in a molecule.
The boiling point of a substance is a measure of its volatility, with lower boiling points indicating higher volatility. In general, the strength of intermolecular forces positively correlates with boiling points.
Now, comparing Cl2 and F2, we find that fluorine gas (F2) is less volatile and has a lower boiling point compared to chlorine gas (Cl2). This is because fluorine atoms are smaller than chlorine atoms, resulting in stronger London dispersion forces in F2. The stronger intermolecular forces in F2 require more energy (higher temperature) to break them, hence a higher boiling point.
Therefore, the correct answer is: F2 (fluorine gas) is less volatile than Cl2 (chlorine gas) since it has stronger intermolecular forces due to its smaller atom size, resulting in a higher boiling point.
