Regardless of the state, the forces which hold an iodine moolecule together are the same for any other covalent bond: the electric force between the two opposite charges (the positive nuclei and the negative electrons).
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.
Van der Waals forces, specifically London dispersion forces, are the main intermolecular forces between iodine molecules (I2). These forces arise from temporary fluctuations in electron distribution around the molecules, leading to weak attractions between them. There are no significant dipole-dipole interactions or hydrogen bonding in iodine molecules.
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.
In the solid state, iodine molecules are held together by intermolecular forces, which create a larger average distance between the atoms compared to when they are in the gaseous state and are free to move independently of one another. The intermolecular forces in the solid, such as Van der Waals forces, result in a longer bond distance between the iodine atoms.

iodine is made from diatomic iodine molecules,the two iodine atoms are covalently bonded with each other.the iodine molecules have dispersion forces so,the crystal is made from the dispersion forces between the iodine molecule.

Iodine dissolves readily in CCl4 due to the presence of London dispersion forces between the iodine molecules and the non-polar CCl4 molecules. These weak intermolecular forces allow for iodine molecules to be dispersed throughout the CCl4 solvent.

Bromine, chlorine, and iodine are all halogens that exist as diatomic molecules (Br2, Cl2, I2) at room temperature. They are held together by weak van der Waals forces, which exist as London dispersion forces due to the temporary dipoles formed by the movement of electrons in the molecules. These intermolecular forces increase in strength as you go down the group from bromine to iodine.
To sublime iodine, the attractive forces that must be overcome are primarily the van der Waals forces, which are weak intermolecular forces resulting from temporary dipoles induced in the iodine molecules. These forces hold the iodine molecules together in the solid state. During sublimation, sufficient energy is required to break these interactions, allowing the iodine to transition directly from a solid to a gaseous state.
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.
Iodine has stronger intermolecular forces.
think in the gaseous phase there are other forces acting atoms of iodine like inter moleculer forces due to wich bond distance increases. in case of gasous state there are no other force acting on the molecule of iodine axcept electrostatic force between two atoms of iodine . so in case of gase elctrostatic force is more than in the case of solid..
