(a)
Interpretation:
The Fischer projection of the stereoisomer of Threonine which has two chiral centers with the configuration 2S,3R has to be drawn.
Concept Introduction:
The two dimensional representation of the molecules is known as Fischer projection. In Fischer projection, the atoms present on the horizontal plane are facing towards the front and the atoms present on the vertical plane are away from the plane.
When the atom is bonded to four different groups, based on the order of priority of the groups present, if it gets clock wise rotation then it is said to be in R-configuration, if the order of priority of the
(b)
Interpretation:
The three dimensional representation of the stereoisomer of Threonine which has two chiral centers with the configuration 2S,3R has to be drawn.
