Question

decoupled C NMR spectrum. Which isomer is that sample? meta a. ortho b. meta Cpara d. can't t tell. All of the isomers would have four peaks. dchudrohromination most rapidly with KOHEOH? 24. (4) Which of the followin urhich f ,ha hich of the following undergoes dehydrobromination most rapidly with KOH/EIOH? la nd. . (H3C) a. b. CH 25. (4) Which of the following compounds could be used to effect the optical resolution of a sample of carboxylic acid A? HO NH2 a. B or D b., C d. Compound A cannot be resolved by any of these reagents.

Explanation / Answer

Separation of racemates into their component enantiomers is a process called resolution.

We kno that enantiomers have identical physical properties, such as solubility and melting point and hence their resolution is a difficult process to accomplish.

However, Diastereomers have different physical properties. So in resolution reaction of a racemate with an enantiomerically pure chiral reagent gives a mixture of diastereomers, which can be easily separated.

For carboxylic acid we used optically active amines.

E : it is not an amine ( so cant be used)

C: it is not optically active

So B and D can be used ( optically active amine)
