Question

Name the isomeric relationship (enantiomers, constitutional isomers, identical, or diastereomers) for each pair of molecules.

and &-á e dua and 3. C! and OH Br- H Br H and ОН H- Br H+Br CH3 CH3

Answer 1

Solution: moon image each other 2 Constitutional isom isomes, is a type of antiomer Enantiomers are Chinal molecules that are Minnon images of one another e molecule R - Conformation and other molecule S-Conformation. Because, R&S minnon image each Constitutional isomers constitutional isomer, is a in which molecules with the same molecules formula but different bonding Connectivity. Identical isomers The isomers with identical formules but distinct structures. Diastereo isomer Dias tenisomes are defined as non- minnon image each other. a structure-I) 1 800 S notation 2 120° notation . (structure-I) same structure. Hence, structure If structure-II are the Therefore, they are - Identical isomers 3 HR- Conformation.. . a t s-Conformation R-Conformation. b y S-Conformation. 2 Hy (Structure-11) 1800 notation enre. The structure - I & Strue tine - I each other, they are Enantiomes. (Mirron) minnon are the image image
