Chemical structure - Wikipedia
A chemical structure of a molecule is a spatial arrangement of its atoms and their chemical bonds. Its determination includes a chemist 's specifying the molecular geometry and, when feasible and necessary, the electronic structure of the target molecule or other solid.

Chemical Structure - Introduction, Types, Examples and …
Chemical Structure is the spatial arrangement of atoms in a molecule. Chemical structure determines the molecular geometry of the molecule. Russian Chemist Alexander Butlerov acknowledged that molecules are not random clusters of atoms and functional groups but are arranged in a concrete pattern.

1.12: Drawing Chemical Structures - Chemistry LibreTexts
The three different ways to draw organic molecules include Kekulé Formulas, Condensed Formulas, and Skeletal structures (also called line-bond structures or line formulas). During this course, you will view molecules written in all three forms.
1.4: Representing structures - Chemistry LibreTexts
Chemical structures are the essential building blocks in organic chemistry. They make up the “words” of every organic chemistry sentence, so it is vital to understand how to read and write structures.
1: Structure and Bonding - Chemistry LibreTexts
The chapter introduces the fundamental concepts of structure and bonding in organic chemistry, emphasizing their importance for understanding molecular behavior and reactivity.
ChemSpider: Search and Share Chemistry - Homepage
A free chemical structure database providing fast text and structure search access to over 130 million structures from hundreds of data sources.
1.12 Drawing Chemical Structures - Organic Chemistry - OpenStax
In the structures we’ve been drawing until now, a line between atoms has represented the two electrons in a covalent bond. Drawing every bond and every atom is tedious, however, so chemists have devised several shorthand ways for writing structures.
Chemical Sketch Tool - RCSB PDB
Use the Chemical Sketch tool to draw or edit a molecule. The resulting SMILES or InChI string may be used to search for matching molecules in the PDB Chemical Component Dictionary. Note that matches will include any chemical component in the dictionary, including polymeric ones like Alanine or Adenosine. Help.
