The Fischer structure for the open chain form of tagatose is to be drawn. 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 asymmetric carbon atoms are arranged according to their configuration in Fisher projection. When two groups on a fisher projection are interchanged, the configuration of chiral carbon also changes from (R) to (S) aur (S) to (R).
