Abstract:
In the title Schiff base mol-ecule, C13H9ClFNO, the benzene rings are twisted slightly with respect to each other, making a dihedral angle of 7.92 (2)°. An intra-molecular O-H⋯N hydrogen bond occurs. In the crystal, an infinite chain is formed along the c-axis direction by π-π stacking inter-actions between the phenyl rings and the six-membered hydrogen-bonded ring of neighboring Schiff base ligands [centroid-centroid distances of 3.698 (2) and 3.660 (3) Å]. Neighboring chains are linked into a three-dimensional supra-molecular structure by C-H⋯O and C-H⋯F hydrogen bonds.

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.

Protection
It defines a protecting group as the masking agent to make the more reactive species inert to a given set of conditions. This concept is depicted via the illustration of liquid flow through different outlets in an assembly of pipes. The analogy helps to understand the role...
