thanks !:)

Answer 1

Aus Priorities are assign according to o atomic number of adjacent atom of chiral center. # Atom with higher atomic number will get high priority, we need to sotate from ③ (where - highest prosity group 2 - 2nd highest u © -) 33d highest

In Fischer Projection cluckwise rotation & 4th brusity group on vertical Line - RJ clockwise rotation & 4th priority group on horizontal Line - S = ls anticlockwise station + 4th priority grogh on vertical line rotation group RJ anticlockwise & 4th priority on horizontal Line -
