    Study Notes

    Stereochemistry Overview

    • Focuses on the spatial arrangement of atoms in molecules and how this affects their properties and reactions.
    • A key subdiscipline of organic chemistry.

    Stereoisomers

    • Stereoisomers share the same molecular formula and bonding connectivity but differ in spatial arrangement.
    • This difference in arrangement leads to distinct physical and chemical properties.

    Meaning of 'Stereo-'

    • The prefix 'stereo-' means three-dimensional or spatial, indicating the importance of the 3D arrangement of atoms.

    Branch Exclusion

    • Stereochemistry does not encompass thermodynamics, which deals with energy and heat changes in chemical processes.

    Dynamic Stereochemistry

    • Studies molecules in motion and explores how their spatial arrangement affects reaction mechanisms and rates.

    Chiral Objects

    • A chiral object cannot be superposed on its mirror image, similar to left and right hands.
    • Chiral molecules often possess at least one asymmetric carbon atom.

    Mirror Images in Chirality

    • The mirror image of an achiral object is indistinguishable from the object itself, meaning it can be superposed.

    Origin of 'Chiral'

    • The term 'chiral' was first used in a scientific context by the chemist Louis Pasteur in relation to molecular asymmetry.

    Etymology of 'Chirality'

    • The word 'chirality' is derived from the Greek word 'cheir', which means 'hand'.

    Non-Chiral Objects

    • A non-chiral object that can be superposed on its mirror image is termed achiral.
