The Fischer Projections of all 2-ketopentoses has to be drawn and among that D-2-ketopentoses, L-2-ketopentoses and enantiomers has to be identified. Concept Introduction: The two dimensional representations of Carbohydrates is known as Fischer Projections. The Ketopentoses contain the formula C 5 H 10 O 5 . The 2-ketopentose contain ketone group at the second carbon. D-ketopentose: The penultimate carbon contains − OH on right side of the structure. The D stands for Dextrorotatory. L-ketopentose: The penultimate carbon contains − OH on left side of the structure. The L stands for Levorotatory. Enantiomers: The stereoisomers which are mirror images and are non-superimposable are known as enantiomers.

Question

3. Name this ether correctly. H₁C H3C CH3 CH3 4. Show the best way to make the ether in #3 by a Williamson Ether Synthesis. Start from an alcohol or phenol. 5. Draw the structure of an example of a sulfide.

Answer 1

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
