Summary
This study details the crystal structure of a chlorinated organic compound, C(9)H(7)ClN(2)O. The analysis reveals a specific dihedral angle between aromatic rings and intermolecular hydrogen bonding in its crystalline form.
Area of Science:
- Crystallography
- Organic Chemistry
- Molecular Structure
Background:
- Understanding the three-dimensional arrangement of atoms in organic molecules is crucial for predicting their properties and reactivity.
- Crystal structure analysis provides precise details on molecular conformation and intermolecular interactions.
Purpose of the Study:
- To elucidate the crystal structure of the title compound, C(9)H(7)ClN(2)O.
- To characterize the dihedral angle between aromatic ring planes and identify hydrogen bonding patterns in the crystal lattice.
Main Methods:
- Single-crystal X-ray diffraction was employed to determine the molecular and crystal structure.
- Analysis of the crystal structure included the measurement of dihedral angles and the identification of hydrogen bond donors and acceptors.
Main Results:
- The dihedral angle between the aromatic ring planes in C(9)H(7)ClN(2)O was determined to be 11.0(2)°.
- Inversion dimers were observed, facilitated by pairs of O-H⋯N hydrogen bonds, forming characteristic R(2)(2)(8) loops in the crystal structure.
Conclusions:
- The crystal packing of C(9)H(7)ClN(2)O is governed by specific dihedral angles and robust intermolecular hydrogen bonding.
- The identified hydrogen bonding motif contributes to the overall stability and organization of the crystal lattice.

02:36Acidity and Basicity of Alcohols and Phenols
22.4K
Like water, alcohols are weak acids and bases. This is attributed to the polarization of the O–H bond making the hydrogen partially positive. Moreover, the electron pairs on the oxygen atom of alcohol make it both basic and nucleophilic. Protonation of an alcohol converts hydroxide, a poor leaving group, into water—a good one. The two acid–base equilibria corresponding to ethanol are depicted below.

02:23Structure and Nomenclature of Alcohols and Phenols
23.0K
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.

01:10Hydrolysis of Chlorobenzene to Phenol: Dow Process
4.2K
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...

01:13Five-Membered Heterocyclic Aromatic Compounds: Overview
5.9K
Heterocyclic aromatic compounds are cyclic compounds that are aromatic and have one or more heteroatoms—atoms other than carbon, in the ring. Depending upon the number of atoms present in the ring, they can be either five or six-membered. Examples of five-membered heterocyclic aromatic compounds include pyrrole, furan, thiophene, and imidazole. Pyrrole consists of one nitrogen atom having one lone pair of electrons. Furan and thiophene have one oxygen and one sulfur heteroatom,...

01:25Basicity of Heterocyclic Aromatic Amines
7.1K
Heterocyclic amines, where the N atom is a part of an alicyclic system, are similar in basicity to alkylamines. Interestingly, the heterocyclic amine having a nitrogen atom as part of an aromatic ring has much less basicity than its corresponding alicyclic counterpart. For this reason, as presented in Figure 1, piperidine (pKb = 2.8) is significantly more basic than pyridine (pKb = 8.8).

01:11Nomenclature of Aromatic Compounds with Multiple Substituents
11.0K
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...
