S configuration h vs ch3
WebIf you had started from the same R configuration but oriented H in the front and CH3 in the back, it would have been S configuration. Let's call this S configuration A, where you just … WebIn organic chemistry, the Cahn–Ingold–Prelog (CIP) sequence rules (also the CIP priority convention; named for R.S. Cahn, C.K. Ingold, and Vladimir Prelog) are a standard process to completely and unequivocally name a stereoisomer of a molecule.: 26 The purpose of the CIP system is to assign an R or S descriptor to each stereocenter and an E or Z descriptor …

WebThe first conformation has one CH 3 /CH 3 gauche interaction which brings 3.8 kJ/mol energy of destabilization. The second conformation is three pairs of eclipsing groups: one H/H = 4 kJ/mol and two H/CH 3 = 2 x 6 kJ/mol = 12 kJ/mol. In total, 12+4 = 16 kJ/mol. The energy difference is 16 – 3.8 = 12.2 kJ/mol.
