- -Sketch the Fischer projection and make a model of each stereoisomer (R and S) of the alcohol 2-butanol, CH3CHOHCH2CH3. Also sketch the monosaccharide glyceraldehyde, HOCH2CHOHCHO. Prioritize the four groups attached to the stereocenter with 1 being the highest priority and 4 being the lowest priority.D-Mannose differs in configuration from D-glucose at carbon-2. Draw chair conformations for α-D-mannopyranose and β-D-mannopyranose. Label the anomeric carbon in each.What is the correct assignment of chirality at C2 and C4 for the following molecule
- Stereochemistry in biological molecules is often denoted by the D‑ and L‑ convention, instead of the ?‑R‑ and ?‑S‑ configurations determined by the Cahn–Ingold–Prelog methodology. Historically, the glyceraldehyde enantiomer that rotated plane polarized light clockwise was arbitrarily designated as D and the other enantiomer was designated as the L configuration. The D‑glyceraldehyde Fischer projection is shown. D‑glyceraldehydeFor molecule CH3CH2CH(OH)CH3a. Identify chiral centreb.

What is the difference between stereocenters and chiral centers?Because there is usually slow interconversion between the two isomeric forms at room temperature. Because there is usually rapid interconversion between the two isomeric forms at room temperature. Because chirality only exists with the tetrahedral carbon atoms. Because four bonds a are needed to define a stereogenic center.a).Consider the Fischer projections of the following pair of stereoisomers.
