Question 1 Report

The molecular lattice of iodine is held together by
Answer Details
The molecular lattice of iodine is held together by van der Waal's forces. Iodine is a diatomic molecule made up of two iodine atoms. The atoms are held together by a covalent bond formed by sharing electrons between them. In the solid state, the iodine molecules are arranged in a lattice structure held together by weak intermolecular forces called van der Waal's forces. These forces arise due to temporary fluctuations in the electron density around the atoms, which induce dipole moments in neighboring molecules. The dipole moments attract each other, creating a weak force that holds the molecules together in the lattice structure. Therefore, out of the options given, van der Waal's forces are responsible for holding the molecular lattice of iodine together.
