The Fischer projections of all 2-ketopentose need to be drawn along with their descriptions as D-2-ketopentoses, L-2-ketopentoses and enantiomers. Concept Introduction: A convention used to represent a 3-D stereoformula in 2-D representation is said to be Fischer projections. In this projection, the vertical lines represent bonds below the plane of the paper and horizontal lines represents bonds above the plane of the paper. For a D-sugar, the -OH group attached to the bottom chiral carbon is present at the right-hand side whereas for L-sugar it is present at left-hand side.

Question

Definition Definition Organic compounds that have a carbonyl group, C = O, as their functional group. The carbonyl group in ketones is placed somewhere in the middle of the molecular structure, which means, the C=O is attached to two alkyl groups or benzene rings. Just like all other homologous series, the naming of ketones is done using a common suffix “-one”. The general molecular formula is C n H 2n O. Functional group of a ketone
