geminal Explanation: Es un prefijo (gem-) que se usa para cuando dos sustituyentes se encuentran en el mismo carbono. Se usa mucho en resonancia magnética nuclear (RMN) para referirse a un acoplamiento entre protones geminales (https://www.chem.wisc.edu/areas/reich/nmr/05-hmr-04-2j.htm). También es un prefijo en química orgánica como se ve en las referencias de abajo. -------------------------------------------------- Note added at 16 hrs (2019-08-12 17:41:10 GMT) -------------------------------------------------- También ver esto como referencia: https://chem.libretexts.org/Ancillary_Materials/Reference/Or... https://es.wikipedia.org/wiki/Geminal Reference: http://www.chem.ucla.edu/~harding/IGOC/G/geminal.html |

| Reference: Thorpe–Ingold effect, gem-dimethyl effect, or angle compression Reference information: Thorpe–Ingold effect - Wikipedia https://en.wikipedia.org/wiki/Thorpe–Ingold_effect The Thorpe–Ingold effect, gem-dimethyl effect, or angle compression is an effect observed in chemistry where large substituents favor ring closure and intramolecular reactions. The effect was first reported by Beesley, Thorpe, and Ingold in 1915 as part of a study of cyclization reactions. It has since been generalized to many areas of chemistry. -------------------------------------------------- Note added at 1 hr (2019-08-12 02:54:34 GMT) -------------------------------------------------- efecto gem-dialquílico: universidad nacional del sur - Repositorio Institucional de la ... repositoriodigital.uns.edu.ar/bitstream/123456789/.../TESIS%20Scoccia%20Jimena.pdf J Scoccia - 2015 - Efecto de Thorpe-Ingold, en el que los sustituyentes con mayor volumen estérico que los hidrógenos metilénicos generan una compresión en el ángulo interno. furanos - Semantic Scholar https://pdfs.semanticscholar.org/.../b910ab4ee8bcb58de6968a8... - DS TERRÉS - estabilización por efecto anomérico.
