Which of the following is NOT characteristic of hydrogen bonding?
Correct Answer: C.The other atom involved in the hydrogen bond (not the hydrogen atom) must be covalently bonded to a hydrogen atom.
Answer choice C. is not necessary for the formation of a hydrogen bond. A classic example is that of ethers. Ethers are water soluble because the oxygen in ether, which is covalently bonded to two carbons, can hydrogen bond with the hydrogen in H2O. Note regarding answer choice C.: the 3-D shapes of many proteins and DNA is due in part to intramolecular H-bonds.
