(ii) Substituents on chair conformers prefer to occupy equatorial positions due to the increased steric hindrance of axial locations.
WebKnowing the relative stabilities of various compounds allows us predict how likely they are to react with other compounds, and tells us about the details of these reactions. Stability tends to be inversely related to reactivity (more stable compounds are less likely to undergo chemical reactions). :) 2 comments ( 9 votes) Upvote Downvote Flag Maiar Web6 hours ago · The latest Newcastle United headlines including updates on Anthony Gordon, Allan Saint-Maximin, Miguel Almiron and more ahead of the clash with Aston Villa
