Intermolecular Forces

Which of the following accurately describes intermolecular forces?

• weak attractions between molecules

• weak bonds that form new substances

• strong bonds that can not be broken

• any bond that shares electrons

Which of the following is an example of an intermolecular force?

• Ionic bonds

• Covalent bonds

• Hydrogen bonds

• James Bond

All intermolecular forces involve...

• bonding by sharing electrons

• bonding by transferring electrons

• hydrogen atoms that are involved in a bond

• slightly positive and slightly negative poles

In order for a molecule to be polar, it must have...

• differences in electronegativity and lack of symmetry

• at least two different atoms, regardless of the arrangement

• a hydrogen atom bonded to a fluorine, oxygen or nitrogen

• electrons
