What I Know? (Week 5)

A heat of hydration is the result of favorable interaction between the cations and anions of an ionic compound with water. The nature of this attraction is?

• h-bonding

• ion-dipole forces

• dispersion forces

• dipole-dipole interaction

The strength of London dispersion forces is a function of the molar mass of substance. As the molar mass increases the strength of interaction between molecules due to the dispersion forces

• increase

• decrease

• remain the same

• cannot be measure

It results when an ion or polar molecule is placed near an atom or a nonpolar molecule such that the electron distribution is distorted by the force exerted by the said substances

• H-bonding

• ion-dipole forces

• dispersion forces

• dipole-dipole interaction

Attractive forces between polar molecules where the positive end of one molecule aligns to the negative end of another molecule

• ion-dipole

• dipole-dipole

• dispersion forces

• ion-induced dipole

The strongest among the intermolecular forces

• ion-dipole

• H-bonding

• dipole-dipole

• dipole-induced dipole
