(a)
Interpretation:
Structure of the enamine need to be identified along with the observed enantiomeric excess of 83% obtained when enamine is treated with methyl iodide followed by hydrolysis need to be explained.
Concept introduction:
When an optically pure
If it is not symmetrical then more isomers are formed.
(b)
Interpretation:
Structure of the enamine need to be identified along with the observed enantiomeric excess of 83% obtained when enamine is treated with methyl iodide followed by hydrolysis need to be explained.
Concept introduction:
When an electrophile(methyl iodide) attacks the optically active enamine, the attack of the methyl group will be substituted where there is less steric hindrance forming the product.

- A mixture of C7H12O2, C9H9OCl, biphenyl and acetone was put together in a gas chromatography tube. Please decide from the GC resutls which correspond to the peak for C7,C9 and biphenyl and explain the reasoning based on GC results. Eliminate unnecessary peaks from Gas Chromatography results.arrow_forwardIs the molecule chiral, meso, or achiral? CI .CH3 H₂C CIarrow_forwardPLEASE HELP ! URGENT!arrow_forward
