The word "isomeric" is spelled with the letter "i" followed by "s" and "o," then "m" and "e" and "r" followed by "i" and "c." The IPA phonetic transcription of this word is /aɪsəˈmɛrɪk/ which can be broken down into individual sounds: "ai" for the sound of the letter "i," "s" as "s," "uh" as "ə," "m" as "m," "eh" as "ɛ," "r" as "r," "ih" as "ɪ," and finally "k" as "k." This word refers to molecules with the same chemical formula but different structures.
Isomeric refers to a property or characteristic of molecules that have the same chemical formula but differ in their arrangement or connectivity of atoms in the molecule. Isomeric molecules possess similar chemical compositions, meaning they contain the same types and numbers of atoms. However, these atoms are organized in distinct ways, resulting in different chemical properties and potentially different physical properties as well.
The concept of isomerism arises due to the phenomenon of spatial arrangement in molecules. Isomers may differ in the position of functional groups or the sequence in which atoms are bonded to each other. These variations in connectivity lead to differences in the overall shape and structure of the molecule, affecting its behavior and reactivity.
Isomers can be broadly classified into two main types: structural isomers and stereoisomers. Structural isomers display variations in the arrangement of atoms, such as different branching patterns or different functional group positions. Stereoisomers, on the other hand, have the same structural arrangement but differ in the spatial orientation of their atoms.
The study of isomerism is of utmost importance in chemistry, as it aids in understanding the distinct properties and behaviors of different molecules derived from the same formula. Isomeric compounds often exhibit contrasting chemical reactivity, biological activity, and physical characteristics, which makes their differentiation crucial in various disciplines, from medicinal chemistry to materials science.
Noting substances having the same percentage composition, but differing in their physical properties, this difference being due to different arrangement of the atoms in the molecule.

The word "isomeric" is derived from the Greek prefix "iso-", meaning "equal" or "same", and the word "meric", which comes from the Greek root "meros" meaning "part" or "portion". Combining these two elements, "isomeric" refers to substances or molecules having the same parts or composition but different arrangement or structure.
