O The reaction went to completion, but a side product present along with the alcoholproduct. is The reaction went to compleson. Only product is present in the crude product The reacbondd not occur only starting materal is presentin crude produet. o The reaction did not go to completion. Starting material is ssu present in the cnade product mixture. QUESTION 5

Explanation / Answer

4. For the given reduction of ketone to alcohol

From the given tlc plate we could say that,

- the reaction did not go to completion, strating material is present in crude product mixture

5. Recrystalllization resulted in,

- Recrystallization resulted in a pure sample of strating material

8. From the spectroscopic data,

functional group present

- ketone

9. Molecular formula = C10H12O2, degree of unsaturation = 5

10. The structure matching the data would be,

D
