(a)
To determine: The fisher projection for the given perspective formula.
Interpretation: The given perspective formula is to be converted into fisher projection.
Concept introduction: An asymmetric carbon atom is represented as a cross in Fisher projection. The carbon chain is kept along the vertical line. The groups attached to asymmetric carbon atoms are arranged according to their configuration in Fisher projection.

H2O2/Fe3+arrow_forwardDetermine the # of chiral centers. Determine the most stable chair conformation then indicate which are equatorial and which are axial.arrow_forwardIn Fischer projections, the horizontal bonds represent groups projecting forward (on wedges) and the vertical bonds represent groups projecting backwards (on dashes). True or False True Falsearrow_forward
- Draw Fischer projection and determine the configurationarrow_forwardTasks Demonstrate the usefulness of Fischer projections by showing how it is easy to determine isomeric relationship between two structures. 1. Convert both isomers in Figure 8 to Fischer projections. 2. Identify the stereoisomeric relationship between the isomers. Briefly explain the process.
