Background:
- Understanding molecular conformation is crucial for predicting chemical properties.
- Hydrogen bonding plays a significant role in stabilizing molecular structures and influencing crystal packing.
Purpose of the Study:
- To elucidate the molecular conformation and hydrogen bonding network of the title compound, C(10)H(8)ClNO(3).
- To analyze the crystal structure and intermolecular interactions.
Main Methods:
- Single-crystal X-ray diffraction was employed to determine the molecular and crystal structure.
- Analysis of intramolecular and intermolecular hydrogen bonds.
Main Results:
- The compound C(10)H(8)ClNO(3) exhibits stabilization via two intramolecular hydrogen bonds: an O-H⋯O bond within the maleamic acid unit and a C-H⋯O bond between the amide and phenyl groups.
- The maleamic acid unit is nearly planar, with a dihedral angle of 15.2° relative to the phenyl ring.
- Intermolecular N-H⋯O hydrogen bonds form C(7) chains in the crystal structure.
Conclusions:
- The molecular conformation is significantly influenced by intramolecular hydrogen bonding.
- The observed crystal packing is dictated by intermolecular hydrogen bonds, leading to chain formation.

Naming Acid Halides
The IUPAC and common names of acid halides are derived from the corresponding carboxylic acids, by changing “ic acid” to “yl halide.” For example, as shown below, the IUPAC name ethanoyl chloride is derived from ethanoic acid, and the common name, acetyl chloride, is obtained from acetic acid.

01:07Acid Halides to Amides: Aminolysis
Aminolysis is a nucleophilic acyl substitution reaction, where ammonia or amines act as nucleophiles to give the substitution product. Acid halides react with ammonia, primary amines, and secondary amines to yield primary, secondary, and tertiary amides, respectively.
In the first step of the aminolysis mechanism, the amine attacks the carbonyl carbon of the acyl chloride to form a tetrahedral intermediate. In the second step, the carbonyl group is re-formed with the elimination of a chloride...

01:16IUPAC Nomenclature of Aldehydes
Aldehydes are named based on the systematic nomenclature rules set by the IUPAC. For acyclic aldehydes, the longest carbon chain containing the aldehydic (–CHO) group is considered the parent chain. The aldehyde is named by replacing the last letter “e” in the hydrocarbon name with “al”. For instance, a simple, seven-carbon-membered acyclic aldehyde is called heptanal, derived from heptane. The carbon chain is numbered starting from the aldehydic carbon, although the aldehydic carbon’s locant...
01:19Amines to Amides: Acylation of Amines
Various carboxylic acid derivatives (such as acid chlorides, esters, and anhydrides) can be used for the acylation of amines to yield amides. The reaction requires two equivalents of amines. The first amine molecule functions as a nucleophile and attacks the carbonyl carbon to produce a tetrahedral intermediate. This is followed by the loss of the leaving group and restoration of the C=O bond.
Next, the second equivalent of amine serves as a Brønsted base and deprotonates the quaternary amide...
