Question

1. what type of intermolecular force forms during the solvation process when kbr dissolves in water?

covalent bonding
dipole-dipole forces
hydrogen bonding
ion-dipole forces

Explanation:

When KBr (an ionic compound) dissolves in water, KBr dissociates into \(K^+\) and \(Br^-\) ions. Water is a polar molecule (has a dipole moment). The interaction between the ions (\(K^+\) or \(Br^-\)) and the polar water molecules is called ion - dipole forces. Covalent bonding is an intramolecular force (within a molecule), dipole - dipole forces act between polar molecules (not ions and molecules), and hydrogen bonding is a specific type of dipole - dipole force involving H bonded to F, O, or N (not relevant here as KBr is ionic).

Answer:

D. ion - dipole forces
