Chapter 1: Problem 66

The specific arrangement of atoms that characterize a particular stereoisomer is known as (a) tautomer (b) conformation (c) configuration (d) geometry

Short Answer

Expert verified
Answer: Configuration

Step by step solution

01

Option (a) Tautomer

Tautomers are isomers that can rapidly interconvert by the movement of a hydrogen and the movement of a double bond. Tautomerism is a kind of isomerism, but is not specifically related to the arrangement of atoms that characterizes a stereoisomer.
02

Option (b) Conformation

Conformation refers to the three-dimensional arrangement of the atoms in a molecule that results from rotation around single bonds. Conformational isomers are not true isomers as they are not energy minima on a potential energy surface, and they rapidly interconvert.
03

Option (c) Configuration

Configuration refers to the fixed arrangement of atoms in a molecule that arises due to restricted rotation around a bond, which can be a double bond, ring structure, or presence of a chiral center. Configuration describes the spatial arrangement of atoms that characterizes a particular stereoisomer. This seems to be the correct answer.
04

Option (d) Geometry

Geometry refers to the general structural arrangement of the atoms in a molecule, and is not specific to stereoisomers. Geometric isomerism can occur in compounds with double bonds. It is a type of configuration, but in itself, is not the term that accurately describes the specific arrangement of atoms in a stereoisomer.
05

Final Answer

Based on the analysis, the correct answer to this question is (c) Configuration. It is the term that best describes the specific arrangement of atoms that characterizes a particular stereoisomer.
