Definitions

1. Describing a chemical compound in which a single atom or group of atoms has been replaced or substituted within a molecular structure

Etymology: "Monosubstituted" is a straightforward chemistry-style compound, built from the Greek prefix "mono-", meaning "one" or "single", and the past participle of "substitute". The "substitute" part comes from Latin "substituere", literally "to put in place of", combining "sub-" (under, in place of) with "statuere" (to set up or place). A substance that has had exactly one of its atoms or groups swapped for another is described with this word, which places "one" on the front of an older verb meaning "replaced".

Synonyms: single-substituted, one-substituted, monosubstituent, single replacement, single modified
