Question

Use the Fischer projection below to answer the following questions сн. Br- H H- Br CH,CH, (a) Write the IUPAC name for this molecule using the R/S notation (b) Draw the skeletal structure of the mirror Image, le the enantiomer, of the molecule whose Fischer projection is given above. (Show one wedge bond, one dashed bond, and two sticks attached to the chiral carbon. Show the hydrogen atom bonded to the chiral carbon atom as either a wedge or dash to establish stereochemistry. Do not show other hydrogen atoms.) Marvin JS o Help

Answer 1

solution CH3 R H . Brf -BY 222222222 си, сна IUPAC Name :- (2R, 3R) - 1, 2.dibromopentane CH₂ (b) By H ť H HI Br Сн, с. 000 CH₂ CH₂ o required skeletal enantiomer. structure is the given BY CH₂ CH3h Til Br

(C) Diastereomer is given by Сн, I Br since it is not mine image, not super- - imposible en original Structure, hence et is diastereomer. I H. CH₂ CH₂ So, the required skeletal 390 structure :- PPPPPPINSIPPERS SINER CH₂ CH3 I CH3 Tall Br 1 H AK given meso molecule form (d) the enantiomer of the in question (b) is not So, it is chiral.
