Summary
This study details the crystal structure of C(22)H(18)O(2), revealing molecular geometry and intermolecular interactions. The research highlights how molecules form chains through specific hydrogen bonds in the crystal lattice.
Area of Science:
- Crystallography
- Organic Chemistry
- Materials Science
Background:
- Understanding molecular structure and intermolecular forces is crucial in chemistry.
- Crystal engineering aims to design materials with desired properties based on molecular packing.
Purpose of the Study:
- To determine the crystal structure of the title compound, C(22)H(18)O(2).
- To analyze the molecular geometry, including inter-planar angles.
- To investigate intermolecular interactions and their role in crystal packing.
Main Methods:
- Single-crystal X-ray diffraction was used to elucidate the crystal structure.
- Analysis of crystallographic data to determine molecular symmetry and atomic coordinates.
- Identification and characterization of intermolecular interactions, such as C-H⋯O bonds.
Main Results:
- The asymmetric unit contains one half-molecule, with the complete molecule generated by a twofold rotation axis.
- Specific inter-planar angles were measured between the carbonyl group, methyl-substituted phenyl ring, and central ring (23.67(7)° and 50.74(8)°).
- Molecules form infinite chains along the b-axis via intermolecular C-H⋯O interactions, forming R(2)(2)(10) graph-set motifs.
Conclusions:
- The crystal structure of C(22)H(18)O(2) has been successfully determined.
- The study provides insights into the conformational preferences and packing arrangements of the molecule.
- Intermolecular C-H⋯O interactions are key in directing the self-assembly of molecules into one-dimensional chains.

02:23Structure and Nomenclature of Alcohols and Phenols
Overview
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.

01:27Benzene to Phenol via Cumene: Hock Process
The synthesis of phenol from benzene via cumene and cumene hydroperoxide is called the Hock process. First, a Friedel–Crafts alkylation reaction of benzene with propene gives cumene. Then cumene forms cumene hydroperoxide via a radical chain reaction. In the chain initiation step, the benzylic hydrogen is abstracted to give a benzylic radical. In the chain propagation step, the benzylic radical reacts with an oxygen diradical to form a cumene hydroperoxide radical. The cumene hydroperoxide...
01:37NMR Spectroscopy of Benzene Derivatives
Simple unsubstituted benzene has six aromatic protons, all chemically equivalent. Therefore, benzene exhibits only a singlet peak at δ 7.3 ppm in the 1H NMR spectrum. The observed shift is far downfield because the aromatic ring current strongly deshields the protons. Any substitution on the benzene ring makes the aromatic protons nonequivalent, and the protons split each other. The peak is, therefore, no longer a singlet and the splitting pattern and their associated coupling constants depend...
01:23Nomenclature of Aromatic Compounds with a Single Substituent
Benzene is the simplest aromatic hydrocarbon or arene. The IUPAC names for simple monosubstituted benzene derivatives are derived by adding the substituent's name as a prefix to the parent benzene. For example, halobenzene, where the halogen could be fluoro (F), chloro (Cl), bromo (Br), and iodo (I).
01:11Nomenclature of Aromatic Compounds with Multiple Substituents
When more than one substituent is present on the benzene ring, the IUPAC nomenclature depends on the number of substituents present.
For disubstituted benzene derivatives, with two groups attached to the benzene ring, three constitutional isomers are possible. For example, consider dimethyl benzene, often called xylene, where the second methyl group can be substituted at the second, third, or fourth carbon. The relative position of the substituents is represented by prefixes ortho, meta, or...

01:10Hydrolysis of Chlorobenzene to Phenol: Dow Process
Simple aryl halides do not react with nucleophiles under normal conditions. However, the reaction can proceed under drastic conditions involving high temperatures and high pressure to give the substituted products. For example, chlorobenzene is converted to phenol using aqueous sodium hydroxide at 350 °C under high pressure by the Dow process. The reaction follows an elimination-addition mechanism involving a benzyne intermediate. Here, the chloride ion is eliminated to generate the benzyne...
