Talk:Stereochemistry

i think that the place of numbers 2, 3 should be replaced by 1, 4 in the right figure, as they r related to the vertical lines, they should be directed to the backword direction.

This has to be one of the most important chemistry articles in the encyclopedia. Please, lets elevate it in priority and get some subject matter experts to attend to this. One cannot possibly link to it in this shape. Leprof 7272 (talk) 03:41, 11 May 2014 (UTC)

:{{ping| Nicl0728}}. You are an undergrad doing homework on a topic where you are inexpert, so please stick with textbook references. Stereochemistry is a very mature area, and you are very inexperienced. See WP:TERTIARY for the guideline. Standard grad level organic textbooks should be sufficient. --Smokefoot (talk) 13:11, 3 November 2024 (UTC)

Any opinions on these two schemes?:

Image:Isomerism.svgs. Stereochemistry focuses on stereoisomers.]]

File:Stereoisomer are of two types, enantiomers vs diastereomers.svg.

My preference is for the simpler one but maybe I am missing something. Also, the article is not about "isomers" per se, but stereoisomers.--Smokefoot (talk) 14:27, 5 December 2024 (UTC)

:Well, upon reflection, those schemes belong in isomers, not stereochemistry.--Smokefoot (talk) 14:44, 6 December 2024 (UTC)

With regards to stereochemistry, it is useful to review the organization of that theme in the very mature textbook on organic chemistry, which spans about 100 pages (page numbers indicated to indicate emphasis given each topic):

OPTICAL ACTIVITY AND CHIRALITY page 136

Dependence of Rotation on Conditions of Measurement 139

What Kinds of Molecules Display Optical Activity? 140

Creation of a Stereogenic Center 153

The Fischer Projection 153

Absolute Configuration 154

The Cahn–Ingold–Prelog System 155

Methods of Determining Configuration 158

The Cause of Optical Activity 162

MOLECULES WITH MORE THAN ONE STEREOGENIC CENTER 164 (epimers)

Asymmetric synthesis 167

Methods of Resolution 172

Optical purity 179

CIS–TRANS ISOMERISM 182

Cis–Trans Isomerism Resulting from Double Bonds 182

Cis–Trans Isomerism of Monocyclic Compounds 186

Cis–Trans Isomerism of Fused and Bridged Ring Systems 188

Out–In Isomerism (bicyclic systems with,e.g. C-H pointing inside vs outside) 189

Enantiotopic and Diastereotopic Atoms, Groups, and Faces 191

Stereospecific and Stereoselective Syntheses 194

CONFORMATIONAL ANALYSIS 195

Conformation in Open-Chain Systems 197

Conformation in Six-Membered Ring 203

Conformation in Six-Membered Rings Containing Heteroatoms 209

Conformation in Other Ring 211

Molecular Mechanics 213

STRAIN 216 (does not seem so relevant to stereochemistry to me at least)

Strain in Small Rings 217

Strain in Other Rings 223

Unsaturated Rings 226

Strain Due to Unavoidable Crowding 230-233

One lesson is that Wiki-chem covers these topics pretty well. March massively emphasizes chirality etc. Another lesson: our article on stereochemistry is too focused on isomers and rotamers, and not enough on cyclic systems. --Smokefoot (talk) 14:44, 6 December 2024 (UTC)
