Which of the following statements about water is incorrect?
A) It is a small,polar molecule with a low dielectric constant.
B) It has a marked dipole moment.
C) It is largely hydrogen bonded,although any single H-bond exists only for a very short period of time (~10-12 s ) .
D) Acid-base reactions are very fast due to the mobility of hydronium ions in water which is a consequence of the ability of individual protons to "jump" from one water molecule to another.
E) It has a bent geometry with each O─H bond approximately 0.958 Å long and with an O─H bond energy of approximately 460 kJ/mol.
