(a)
To determine: If the compound is chiral; it’s most symmetric conformation and asymmetric carbon atoms (to be marked by a star) and mirror planes if possible.
Interpretation: The validation of the fact that the given compound is chiral is to be stated; most symmetric conformation of the compound and any mirror plane if possible are to be drawn and asymmetric carbon atoms are to be marked by star.
Concept introduction: An asymmetric carbon atom is represented as a cross in Fisher projection. The carbon chain is kept along the vertical line. The groups attached to asymmetric carbon atoms are arranged according to their configuration in Fisher projection. The enantiomers of a chiral compound can be named with the help of right hand and left hand configuration. In fisher projection, chiral carbon atom is represented by a cross. When two groups on a fisher projection are interchanged, the configuration of chiral carbon also changes from (R) to (S) aur (S) to (R).

- Q1: For each molecule, assign each stereocenter as R or S. Circle the meso compounds. Label each compound as chiral or achiral. OH HO CI Br H CI CI Br CI CI Xf x f g Br D OH Br Br H₂N R. IN Ill I -N S OMe D II H CO₂H 1/111 DuckDuckGarrow_forwardThese are synthesis questions. You need to show how the starting material can be converted into the product(s) shown. You may use any reactions we have learned. Show all the reagents you need. Show each molecule synthesized along the way and be sure to pay attention to the regiochemistry and stereochemistry preferences for each reaction. If a racemic molecule is made along the way, you need to draw both enantiomers and label the mixture as "racemic". All of the carbon atoms of the products must come from the starting material! ?
