Question

All of the following are intermolecular forces exist in different types of molecular compounds. Which of the following exists in all molecules? Dipole-dipole Dispersion forces Ion-dipole Hydrogen bonding

Answer 1

Dispersion forces, also known as London dispersion forces, are the only intermolecular force that exists in all molecules, regardless of whether they are polar or nonpolar. These forces arise due to temporary fluctuations in electron density within a molecule, which induce temporary dipoles in neighboring molecules. These temporary dipoles lead to weak attractions between the molecules, known as dispersion forces.Dipole-dipole forces occur in polar molecules, where there is a permanent dipole moment due to the unequal sharing of electrons between atoms.Ion-dipole forces occur between an ion and a polar molecule, typically in solutions where ionic compounds are dissolved in polar solvents.Hydrogen bonding is a special type of dipole-dipole interaction that occurs when hydrogen is bonded to highly electronegative atoms like nitrogen, oxygen, or fluorine, and is attracted to lone pairs of electrons on other electronegative atoms.Therefore, the correct answer is Dispersion forces.
