Cohesion: Hydrogen Bonds Make Water Sticky Show
Water has an amazing ability to adhere (stick) to itself and to other substances. The property of cohesion describes the ability of water molecules to be attracted to other water molecules, which allows water to be a "sticky" liquid. Hydrogen bonds are attractions of electrostatic force caused by the difference in charge between slightly positive hydrogen ions and other, slightly negative ions. In the case of water, hydrogen bonds form between neighboring hydrogen and oxygen atoms of adjacent water molecules. The attraction between individual water molecules creates a bond known as a hydrogen bond. Recommended textbook solutions Modern Chemistry1st EditionJerry L. Sarquis, Mickey Sarquis 2,184 solutions

Hole's Human Anatomy and Physiology13th EditionDavid N. Shier, Jackie L. Butler, Ricki Lewis 1,402 solutions A water molecule is formed by covalent bonds between an oxygen atom and two hydrogen atoms. The covalent bonds are polar because oxygen is more attractive to electrons than hydrogen, causing the oxygen to have a slightly negative charge and hydrogen to have a slightly positive charge. Since the hydrogen atoms aren't linear and are on the same side, the hydrogen atoms form one pole while the oxygen forms the opposite pole. Since water molecules only have partial charges, they can't form ionic bonds, but hydrogen bonds, which is a force that forms when a hydrogen atom in one polar molecule is attracted to a slightly negative atom of another polar covalent molecule. Although hydrogen bonds are weak, with so many of them per unit volume of water, there are large numbers of hydrogen bonds present, giving it special attractive forces and unique properties. -------------------------------- A water molecule is formed by covalent bonds between an oxygen atom and two hydrogen atoms. The bond between hydrogen and oxygen involves unequal sharing of electron - it is a polar covalent bond. This is because the nucleus of the oxygen atom is more attractive to electrons than the nuclei of the hydrogen atom. Because of the unequal sharing of electrons in water molecules, the hydrogen atoms have a partial positive charge and oxygen has a partial negative charge. Because water molecules are bent rather than linear, the two hydrogen atoms are on the same side of the molecule and form one pole and the oxygen forms the opposite pole. Positively charged particles (positive ions) and negatively charged particles (negative ions) attract each other and form an ionic bond. Water molecules only have partial charges, so the attraction is less but it is still enough to have significant effects. The attraction between water molecules is a "hydrogen bond" Strictly speaking it is an intermolecular force rather than a bond. What property of water molecules allows hydrogen bonds to form among adjacent molecules?The property of cohesion describes the ability of water molecules to be attracted to other water molecules, which allows water to be a "sticky" liquid. Hydrogen bonds are attractions of electrostatic force caused by the difference in charge between slightly positive hydrogen ions and other, slightly negative ions.
How do hydrogen bonds form between adjacent water molecules quizlet?How do hydrogen bonds form between adjacent water molecules? A hydrogen bond is formed between adjacent water molecules when a negative end of one water molecule is attracted to the positive end of another water molecule.
What property of water can be attributed to hydrogen bonding between waters?Water has the highest specific heat capacity of any liquid. Water's high heat capacity is a property caused by hydrogen bonding among the water molecules.
What kind of bonds can form between two adjacent water molecules quizlet?Hydrogen bonding is the bonding between two adjacent water molecules.
