please solve them clear & be sure thank you . 1. (21 points) Is the following compound a meso-compound? If yes, show it in 3D in the box below using wedged and dashed bonds to indicate the substituent bond direction and draw the internal mirror plane of symmetry (if any). (3 points) HOOC-CHOH-CHOH-COOH Draw the 3D structures of the stereoisomers of the compound above. Use wedged and dashed bonds to indicate the substituent bond direction in each stereoisomer. [Hint: if...
Draw a three dimensional structure for each compound, and star all asymmetric carbon atoms. Draw the mirror image for each structure, and state whether you have drawn a pair of enantiomers or just the same molecule twice. Draw the enantiomers of 1,3-dibromobutane and label them as (R) and (S).
3. Consider the real world objects below exterior interior of human of human bod bod A roll of ta A nail A screw Which are chiral, and which are achiral? It is easier to prove an object is achiral than to prove it's chiral. You can prove an object is achiral in two ways a. i. draw its mirror image, and show that the mirror image is superimposable on the original ii. find a plane of symmetry in the original...
5. For the structure, CHO НЕОН H+OH CH,OH (a) Draw all the stereoisomers. (b) Label structure as chiral or achiral. (c) Assign each chiral center as (R) or (S). (d) Give the relationships between the stereoisomers (enantiome (e) Label any meso compounds. 6. Give the structures of the following compounds. Classify the com primary, secondary, or tertiary halide if possible. (a) Sec-butyl chloride (b) Isobutyl bromide (c) Chloroform (d) Tert-pentyl iodide (c) 2,2,2-trichloroethanol (f) Methylene chloride
Highlight, by clicking on, the asymmetric carbons (if any) in each structure. A selected atom will turn green. Indicate whether each compound contains a plane of symmetry (internal mirror plane) or not.
How many asymmetric carbons are present in the compound below? Label each asymmetric carbon in the compound below as R or S. Draw this structure of (S)-1-bromo-1-chioropropane. Take particular care to indicate three-dimensional stereo chemical detail properly. Draw the Fischer projection of (S)-2-bromobutane.
1. Construct a model consisting of a tetrahedral carbon center with four different component atoms attached: red, white, blue, green; each color represents a different group or atom attached to carbon. Does this model have a plane of symmetry (1a)? A plane of symmetry can be described as a cutting plane-a plane that when passed through a model or object divides it into two equivalent halves; the elements on one side of the plane are the exact reflection of the...
1. (12pts) Determine if each compound below is chiral or achiral and circle the label that describes each one. Without using the (R)/(S) system, show work to justify each answer by drawing the mirror image and clearly illustrate whether or not the mirror images are superimposable. - Br НСІ - - - (a) Hvac= - (b) AY (C) - " Нcc - CH3 - - Br - - - Chiral or Achiral Chiral or Achiral Chiral or Achiral Chiral or...
