Question

Please answer a-f!!!

Problem 1: Consider the following pairs of structures. Designate each chirality center as (R) or (S) and identify the relationship between them by describing them as representing enantiomers, diastereomers, constitutional isomers, or two molecules of the same compound. F Н Br (a) Н and CHs Br Hас, СН H (b) and Br Br F CH3 Н. Br Cн Br and (e) НаС F F CH3 H I Br Нас. CH3 Br (d) and F CH3 н F CH3 H Br НаС CH3 CH3 н. (e) and F H H* F Н.С Br H&C H CH3 Br and Br CH3 H

Answer 1

(Page no-01) 7 е яс сиз According to Cahn-Ingold Prelog system, the priorities of groups is as follows: Bobro -> group should be belowe the plane. So, by H + doing one go exchange. af © "Bro Anticlockwise rotation so ses configuration. one exchange 84 CH3 one e one exchange Br=CH2 l's configuration Both paises of compound. @ have same I 'S configuration and they are two A reolecules of same compound.

Both are constitutional Isomers.

[Page no-04) HCAH & HH3 Br Bir CH₂ Booth compounds are not chiral because two same groups are present and therefore, it is not possible to assign any Configuration in them There are no relation deetween them, Both are different compounds.
This question is based on stereochemistry.
