Stereochemistry Basics Quiz

The prefix 'stereo-' in stereochemistry means 'three-dimensionality', indicating the focus on the spatial arrangement of atoms in three-dimensional space.

Stereochemistry involves the study of the relative spatial arrangement of atoms in molecules and their manipulation. It focuses on the relationships between stereoisomers, which have the same molecular formula and sequence of bonded atoms but differ in the geometric positioning of the atoms in space. Stereochemistry is significant in understanding the physical and biological properties of molecules and their reactivity.

Jean-Baptiste Biot made the observation of optical activity in 1815, which marked the beginning of organic stereochemistry history.

<p>Cis–trans isomerism, also known as geometric isomerism, describes certain arrangements of atoms within molecules where the functional groups are on the same side (cis) or on opposing sides (trans) of some plane.</p> Signup and view all the answers

<p>The prefix 'cis' is from Latin, meaning 'this side of', and 'trans' is from Latin, meaning 'the other side of'.</p> Signup and view all the answers

<p>Cis indicates that the functional groups are on the same side of some plane, while trans conveys that they are on opposing (transverse) sides. Cis–trans isomers are stereoisomers, pairs of molecules with the same formula but different orientations in three-dimensional space.</p> Signup and view all the answers

<p>Cis and trans isomers occur in both organic molecules and inorganic coordination complexes.</p> Signup and view all the answers

<p>In general, cis–trans stereoisomers contain double bonds or ring structures, where the rotation of bonds is restricted or prevented. The diastereomer is referred to as cis when the substituent groups are oriented in the same direction, and as trans when the substituents are oriented in opposing directions.</p> Signup and view all the answers
