A second ortho-rhom-bic polymorph of 4-(Pyridin-4-ylmethoxy)phenol [corrected]
Abstract:
The crystal structure of the title compound, C(12)H(11)NO(2), represents a new ortho-rhom-bic polymorph II of the previously reported ortho-rhom-bic form I [Zhang et al. (2009 ▶) Acta Cryst. E65, o3160]. In polymorph II, the six-membered rings form a dihedral angle of 13.8 (1)° [71.6 (1)° in I], and O-H⋯N hydrogen bonds link mol-ecules into chains along [100], whereas the crystal structure of I features hydrogen-bonded centrosymmetric dimers.

Structure and Nomenclature of Alcohols and Phenols
Alcohols are one of the most important functional groups in organic chemistry. The name of alcohol comes from the hydrocarbon from which it is derived. Alcohols are organic molecules containing the functional hydroxyl or –OH group directly bonded to carbon. Phenols have an OH group directly attached to a benzene ring. While alcohols are colorless, phenol is a white crystalline compound with a characteristic "hospital smell" odor.
As with other organic compounds, alcohols and phenols...
ortho–para-Directing Activators: –CH3, –OH, –⁠NH2, –OCH3
Preparation of Diols and Pinacol Rearrangement
The reaction begins with transferring a proton from the acid catalyst to one of the hydroxyl groups, producing an oxonium ion.
