Answer 1

CHOH нь anomerie carbon. a-isomes If the -OH group at the anomerie carbon is. downward, then the corresponding isomer is x- isomer. If the -oh group is pointed cepwardo at anomeric carbon, the corresponding on مد حنomمل و ۵۲ مد . сн он anomaric carbon. Kuvo OH MY Hoy HH Looh CH, 3 B-isomer. H OH KAH Hot & anomeria Carbon. H OH pointed upwards. -Since, oh and-och- group the isomer is ßa isomer. CH2OH Vi он ну 3) Gaisomer. VOH H OH downwards, the isomer Since -OH group pointed dis a - isomer.

H to ou Hosta H 4) L- ioomes. SCH,OH. (assymmetric carbon farthest from -CHO ) For the fees Fischer projection, if the highest. priority group of the assem asymou tric carbong farthest from aldehyde or ketone is at the left. side, the corresponding isomes is La isomes. If the highest priority group is at the right side, the corresponding isomes is D- isomes. @3 Since in this isomer, the Oh grocyo at is at left side, so it is to isomes
