(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.

- What is the configuration of the two chiral centers in the following molecule?arrow_forward1) Below you are given the structures of the disaccharides lactose and trehalose. он он но он но но OH но но OH но он но но OH Lactose Trehalose a. Identify clearly the hemiacetal and acetal groups in these disaccharides and determine for each of these identified groups if they have a- or B-configuration.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
