Covalent bond-ing is anintramolecularinteraction.00310.0pointsDispersion (London) forces result from1.the balance of attractive and repulsiveforces between two polar molecules.2.the formation of a loose covalent link-age between a hydrogen atom connected toa very electronegative atom in one moleculeand another very electronegative atom in aneighboring molecule.3.attraction between molecules in a liquidand molecules or atoms in a solid surface withwhich the liquid is in contact.4.distortion of the electron cloud of an atomor molecule by the presence of nearby atomsor molecules.correct5.attractive forces between a molecule atthe surface of a liquid and those beneathit which are not balanced by correspondingforces from above.Explanation:00410.0pointsWhich of the following can form intermolecu-lar hydrogen bonds?
