What is another word for ring strain?
Pronunciation: [ɹˈɪŋ stɹˈe͡ɪn] (IPA) 
Ring strain refers to the energy that is stored in a cyclic organic compound due to the non-optimal bond angles and bond lengths in the ring structure. These strains cause the molecule to undergo various reactions, including ring-opening reactions and ring contraction. Other synonyms for ring strain include cyclic strain, Baeyer strain, and Pitzer strain. Cyclic strain is the energy necessary to distort a ring structure from its ideal circular form into a non-circular shape. The term Baeyer strain is named after Adolf von Baeyer, who first recognized the phenomenon of ring strain in organic chemistry. Pitzer strain is another term sometimes used to describe ring strain, named after Kenneth S. Pitzer, who further expanded on the concept of cyclic strain.
