- For molecule CH3CH2CH(OH)CH3a. Identify chiral centreb. Draw a pair of enantiomers using 3-dimensional structurearrow_forwardConstruct a model of CH3Br using MolView and answer the following: 1. Can it be superimposed on its mirror image? (Y/N) 2. Does CH3Cl contain a plane of symmetry? (Y/N) 3. Is CH3Cl chiral? (Y/N)arrow_forwardWhat is the configuration at the chiral centers of the Fischer projection of the molecule shown? (The molecule is drawn with C1 at the top and C5 at the bottom.)arrow_forward
- Write the configuration of two chirality centers in 4-chloro-2,3-dimethyl-3-pentanol presented through Fischer projection below in a form of short answer: (3R,4R); (3S,4S); (3R,4S); or (3S,4R).arrow_forwardDraw the Fischer projection for structure I. Circle each chiral group in structure II.arrow_forward(b) (i) Using Fischer projection, draw all the stereoisomers of 3-chloro-2-hydroxypentanoic acid. (ii) Assign the chiral centre(s) with R/S configurations in part (b)(i). Indicate which are enantiomers, diastereomers and meso compounds (if any).arrow_forward
- 2. Assign the absolute configuration for each chiral carbon by writing the carbon number followed by R or S enclosed in parenthesis (e.g. 2R, 3S, 4R, 5S). Answers must be written on the right side of the Fischer projection aligned with the corresponding chiral carbon. 3. Underline the absolute configuration, you have to show that it is italicized by underlining the absolute configuration.arrow_forwardAssign R or S configuration to each chirality center in the following molecules.First assign the configuration of the chirality center closest to the top of the Fischer projection. Then give the configuration of the other chirality center.arrow_forwardWhat is the correct assignment of chirality at C2 and C4 for the following moleculearrow_forward
- please draw the Fischer projections for this compound - star all chirality centers - indicate any mirror planes as dashed lines - assign R/S notation - show priorities 1-arrow_forwardThe structure of 4 isomers of ketopentose are shown. 1) select every structure that is a diastereomer of structure D A, B, or C? 2) select every structure that is a enantiomer of structure C A, B, or D 3) select every structure that is a stereoisomer of structure C A, B, or Darrow_forward2. Draw one regioisomer and one stereoisomer and assign R/S for chiral centers. Galantamine Structurearrow_forward
