WebThe conformations corresponding to the 120 and 240 are: a) Staggered, less stable than the conformation at 180. b) Staggered, more stable than the conformation at 0. c) Eclipsed, more stable than the conformation at 180. d) Eclipsed, more stable than the conformation at 0. e)Two of the above are true. WebA corolary is that additions of electrophiles like bromine to cyclohexene double bonds, which go through related bromonium ions, give the diaxial product, even though this is usually the less stable one. These effects fundamentally arise from the inherent preference of cyclohexanes for the chair over the twist-boat conformation. Hückel Rule. jim wendler\u0027s 5/3/1 strength training program
