WebJul 31, 2024 · If X = H and Y = F (Table 13-3), the enantiomers are not stable at room temperature; if X = H and Y = Br, they are marginally stable; if X = H and Y = I, the rate of loss of optical activity is about 700 times slower than with Y = Br. This is in keeping with the fact that the atomic size of the halogens increases in the order F < Br < I. http://www.ochem.com/tutorials/optical-activity-7-min.html

LaFontaine 7 … WebA meso compound is a stereoisomer with two or more chiral centres but no optical activity due to an internal plane of symmetry. Mesomers are compounds with zero net rotation of plane polarised light. In other words, mesomers are organic molecules that have two chiral carbons that are identical, resulting in zero net rotation. notebook es igual a laptop
