Passage I
An unknown organic compound A is determined to have molecular formula C6H12O and passing it through chiral column does not separate it into enantiomers. A does not react with Br2 nor with cold, dilute alkaline KMnO4. Heating A with concentrated H2SO4 gives product B (C6H10) which can be separated into enantiomers. Ozonolysis of a single enantiomer of B produces C, an optically active keto-aldehyde of formula C6H10O2 which gives positive iodoform test.
Q.
The correct statement regarding C is
- a)Reduction of a pure enantiomer of C with NaBH4 gives achiral product
- b)Reduction of a pure enantiomer of C with NaBH4 gives racemic mixture
- c)Reduction of a pure enantiomer of C with NaBH4 gives a pair of diastereomers
- d)Treatment of a pure enantiomer of C with excess of CH3MgBr followed by acid hydrolysis gives racemic mixture of diols
Correct answer is option 'C'. Can you explain this answer?

Reduction of C with NaBH4:
- When a pure enantiomer of compound C is reduced with NaBH4, it results in the formation of a pair of diastereomers.
- This is because the reduction of a chiral compound like C with a chiral reducing agent like NaBH4 leads to the formation of diastereomers due to the different spatial arrangements of the substituents around the newly formed chiral center.
Diastereomers Formation:
- Diastereomers are stereoisomers that are not mirror images of each other and have different physical and chemical properties.
- In this case, the reduction of the optically active compound C with NaBH4 results in the formation of two diastereomers due to the different orientations of the substituents around the chiral center created during the reduction process.
Explanation:
- The positive iodoform test obtained from compound C indicates the presence of a methyl ketone group.
- The treatment of a pure enantiomer of compound C with excess CH3MgBr followed by acid hydrolysis would lead to the formation of a racemic mixture of diols.
- This is because the reaction with excess CH3MgBr would result in the formation of a mixture of two diastereomeric alcohols, which upon acid hydrolysis, would give a racemic mixture of diols due to the presence of a chiral center and the formation of diastereomers in the reaction.
