Which of the following statements is NOT true about phenol? Select the correct answer below: The aromatic ring delocalizes and stabilizes the negative charge on the oxygen in the phenoxide ion. Therefore, phenols completely dissociate in water. A phenol will generally form stronger hydrogen bonds than nonaromatic alcohols because the oxygen-hydrogen dipole in the hydroxyl group is stabilized by resonance from the aromatic ring. The phenol functional group is a weak acid in water because the hydroxyl group dissociates slightly....

Can you help me identify reagent (i), Compound 8 and
Compound 12 in the reaction scheme?
You have laboratory data on all the compounds in the
synthesis, however the amount of data available to you varies. Some
have the entirety of the spectral data, others have as little as
the elemental analysis. Use the laboratory data to help you
discover which reaction has been performed.
The lab data for Compound 8 and 12 is as
