Question

assign R or S and explain how you get there.

Он н 12 сі н 13 ОН 4CHOH сі -сі НО-н CH,OH

Answer 1

H * cl II HOH cha HO* H CH₂OH ен, он or The carbon with groups are called four as different chiral atoms carbon. The mark carbons are chiral carbons as it has four different groups or atoms. 4 priority order of ligands- ® H oH -ei)- CHO>- CHOH-> "CH₂OH 1 273 moves anti clockwise 4th priority not below the plane or lower -OH) - Chel->-CH₂OH)-H position of fisher representation 1+2+3 moves anti clockwise z = R configuration 4th priority not below the plane cy= R configuration

e-H clete Hot priority of the ligands -OH)eelz=>–<H4OH) -4 ен, он 1 → 2 3 moves clockwise s configuration 4th priority on vertical line
