Organic compounds:   A) Aren't generally soluble in water   B) Have lower boing points than inorganic compounds   C) Form covalent bonds   D) All of these

1. The dipole moment in a water molecule Which statement about hydrogen bonds is NOT true? A) Hydrogen bonds account for the anomalously high boiling point of water. B) In liquid water, the average water molecule forms hydrogen bonds with three to four other water molecules. C) Individual hydrogen bonds are much weaker than covalent bonds. D) Individual hydrogen bonds in liquid water exist for many seconds and sometimes for minutes. E) The strength of a hydrogen bond depends on the linearity of the three atoms involved in the bond. 2. A TRUE statement about hydrophobic interactions is that they: A) are the driving force in the formation of micelles of amphipathic compounds in water. B) do not contribute to the structure of water-soluble proteins. C) have bonding energies of approximately 20-40 Kjoule per mole. D) involve the ability of water to denature proteins. E) primarily involve the effect of polar solutes on the entropy of aqueous systems.

What type of reaction will break down large polymers with the addition of water? A.) exchange reaction B.) dehydration synthesis C.) hydrolysis

Discuss whether the following statement is correct: “An ionic bond can, in principle, be thought of as a very polar covalent bond. Polar covalent bonds, then, fall somewhere between ionic bonds at one end of the spectrum and nonpolar covalent bonds at the other end.”
