JEE · NEET Previous Year Question
The incorrect statement regarding chiarality is [NEET 2022]
Topic: NEET PYQ
Answer: C. Full step-by-step solution below.
- A reaction yields mixture of both enantiomers.
- Bthe product obtained in reaction of haloalkane having chirality at the reactive site shows inversion of configuration.
- Cenantiomers are superimposable mirror image of each other.
- Da racemic mixture shows zero optical rotation.
Correct answer: C
Solution
(c) Enantiomers are non-superimposable mirror images of each other. They have identicalphysical properties, i.e. melting point, boiling point, refracive index etc. and differ only with respect to the rotation of plane polarized light. If one of the enantiomer is dextrorotatory, then the other will be laevorotatory.
