Question

PROBLEM 5-16 For each set of examples, make a model of the first structure, and indicate the relationship each of the other structures to the first structure Esamples of relationships: same compou enantiomer, structural isomer CH COOH СООН Н Но- COOH Но H,C OH H -н (а) Н- CH CH Он COOH

I'm having extreme trouble understanding why the middle one is an enantiomer, and then why the last one is the same. I know why the first is an enantiomer. please explain in detail and simply because im extremely confused :(

Answer 1

Answrr Pischer Hint when we rotate then in the same plane Projection by 10 obtains enatiomer wr rotate Pis cher Projection by 180 in when same the came plane then identical or Contijuration obtains che ck R/s configurotion RKS enqmtiomer S R R R Sqme SO coOH 90r0t9tin CH in thep lan CH3 LRJ OH So, both are engtiomers CH2 Rotate 180 in the plane CH3 LRJ LRJ Same Compoun
