What are the forces in a molecular structure?

What are the forces in a molecular structure?

Torsional strain: Strain between groups on adjacent atoms. A-B-C-D. Worst when eclipsed; best when staggered . Bond angle strain: when a bond angle, A-B-C, diverges from the ideal (180, 120, 109). What are the forces in a molecular structure?. 120 deg. View from here yields view below.

Reactions of Enols and Enolates

Reactions of Enols and Enolates. Ketones and aldehydes are in equilibrium with a small amount of the corresponding enol . This can be problematic, if one desires to produce a stereogenic center a to a C=O.
