It depends. If Fluorine is bonded to Hydrogen then it would be greater, having present Hydrogen Bonding-the strongest Intermolecular Force. Iodine,I2, has many more electrons than fluorine, F2,so London dispersion forces are much stronger explaining why fluorine is a gas and iodine is a solid under standard conditions.

How does intermolecular forces of a substance determine the phase the substance is in?
The strength of the intermolecular forces will determine what phase the substance is in at any given temperature and pressure. Consider the halogens for example, fluorine and chlorine are gases, while bromine is a liquid and iodine is a solid at room temperature. When considering the intermolecular forces present, each of these substances only has London forces, which increase in magnitude with increasing size of the molecules, and size increases as you go down a group in the periodic table. So, fluorine has the smallest intermolecular forces, and iodine has the largest. This explains why these different substances exist in different phases when at room temperature and pressure. The molecules in fluorine, for example, are only slightly attracted to each other, and therefore the substance exists as a gas. The stronger intermolecular forces in bromine, however, hold the molecules close to each other, but not quite strongly enough to prevent the molecules from sliding past each other; this makes bromine a liquid. Finally, in iodine, the intermolecular forces are actually strong enough that the molecules are held in fixed positions relative to each other, thus making iodine a solid.
Why is chlorine and iodine in different states in room temperature?
Chlorine is a gas at room temperature because its molecules have low intermolecular forces between them, allowing them to move freely. Iodine is a solid at room temperature because its molecules have stronger intermolecular forces that keep them closely packed together.
Why iodine not soluble in water?
Iodine is not soluble in water because the intermolecular forces between iodine molecules (Van der Waals forces) are stronger than the forces between iodine and water molecules. This makes it difficult for iodine to break its solid lattice structure and separate into individual ions or molecules that can interact with water.
Why iodine is solid but other halogens are gases?
For a start not all the other halogens are gases only chlorine and fluorine, bromine is a liquid and astatine is also a solid. The increase in boiling/melting point as you go down the group is due to the fact the intermolecular forces get stronger. Halogens are non polar, so the only forces between the molecules are van der waals' forces, these forces come from random movement of electrons, When electrons sway in one direction they make that side slightly more negative than the other forming a temporary dipole, this in turn induces a dipole on the molecule next to it, the slightly negative side is then attracted to the slightly positive side. The more electrons the more random movement of electrons and hence stronger van der waals' forces. Iodine has 106 electrons (its a diatomic molecule), this is alot more than chlorine and fluorine hence why iodine is a solid and the others aren't (excluding astatine).
How do intermolecular forces affect the properties of chlorine and iodine?
Intermolecular forces, such as van der Waals forces, affect the physical properties of chlorine and iodine. Iodine, being larger and having more electrons, has stronger van der Waals forces than chlorine, resulting in a higher boiling point and melting point. Consequently, iodine is a solid at room temperature while chlorine is a gas.
Why boiling point of fluorine is less than iodine?
The boiling point of fluorine is lower than that of iodine primarily due to the differences in molecular size and intermolecular forces. Fluorine, being a smaller molecule with weaker London dispersion forces, requires less energy to transition from liquid to gas compared to iodine, which is larger and has stronger dispersion forces due to its greater number of electrons. Consequently, iodine's higher molecular weight and stronger intermolecular interactions result in a higher boiling point.
At STP fluorine is a gas and iodine is a solid This observation can be explained by the fact that fluorine has?
a lower molecular weight and weaker intermolecular forces compared to iodine. This results in fluorine being a gas at STP, while iodine, with its higher molecular weight and stronger intermolecular forces, exists as a solid at the same conditions.
Why is bromine2 a liquid and Iodine 2 is a solid?
Iodine has stronger intermolecular forces.

This makes it difficult for iodine to break its solid lattice structure and separate into individual ions or molecules that can interact with water.
Will fluorine replace iodine in a reaction?
Fluorine is more reactive than iodine, so fluorine can displace iodine in a chemical reaction to form a compound. This displacement reaction occurs because fluorine has a higher electronegativity and stronger oxidizing ability than iodine.
Why iodine is solid but other halogens are gases?

Which of the intermolecular forces are responsible for the phase behavior of the elemental halogens?
The phase behavior of the elemental halogens is primarily influenced by London dispersion forces, which are the weakest type of intermolecular forces. These forces arise due to temporary fluctuations in electron density, leading to temporary dipoles. As the size and number of electrons increase down the group from fluorine to iodine, the strength of these dispersion forces also increases, resulting in higher boiling and melting points. Consequently, while fluorine and chlorine exist as gases at room temperature, bromine is a liquid, and iodine is a solid.
How do intermolecular forces affect the properties of chlorine and iodine?
Intermolecular forces, such as van der Waals forces, affect the physical properties of chlorine and iodine. Iodine, being larger and having more electrons, has stronger van der Waals forces than chlorine, resulting in a higher boiling point and melting point. Consequently, iodine is a solid at room temperature while chlorine is a gas.
Why is the boiling point of chlorine lower than iodine?
The boiling point of chlorine is lower than that of iodine primarily due to differences in molecular size and intermolecular forces. Chlorine (Cl₂) is a smaller molecule with weaker London dispersion forces compared to iodine (I₂), which is larger and has stronger van der Waals forces due to its greater number of electrons. As a result, less energy is required to overcome the intermolecular forces in chlorine, leading to its lower boiling point.
Why does fluorine have higher charge than iodine?
Fluorine has a higher charge than iodine because fluorine is more electronegative than iodine. This means that fluorine has a greater ability to attract electrons towards itself, resulting in a higher charge. Additionally, fluorine's smaller size allows it to exert a stronger pull on electrons compared to the larger iodine atom.
