Question
Identify the characteristics of intermolecular interactions including hydrogen bonding, ion-dipole, and the
hydrophobic effect.
A solid line represents a covalent bond and a dotted line represents an intermolecular attraction. Select the image or images
that represent a hydrogen bond.
-o----H-C-
-N----H-O
-
H-H
-C----H-F-
A water molecule has polar O-H bonds that result in regions of partial pasitive charge (hydrogen atoms) and a region of
partial negative charge (oxygen atom with lone pains). Place the Na* and CI ions where H,0 molecules are properly
oriented to form ion-dipole interactions.
