13. Isolation of trimyristin from nutmeg is an example of
Answer: Solid-liquid extraction:
The extraction process involves, the grounding of nutmeg seeds into powder and then extracted with tert-butyl.methyl ether. Solid power of nutmeg is extracted into tert-butyl methyl ether, which results in trimyristin.
This process is solid-liquid extraction.
Hence, the correct answer is: Solid-liquid extraction.
14) Cyclohexanone -----> Cyclohexanol
A plate: There is no difference between the S and R, therefore, there is no reaction occurred.
B plate: There is a clear difference in the Rf value for S and R. The starting material is not seen in the reaction mixture and a new spot appearing at a lower Rf value. Which indicates the formation of product cyclohexanol.
Hence, this corresponds that the reaction went to completion.
C Plate: The reaction mixture spot contains both the starting material as well as product. Therefore, this indicates that the reaction is occurring but not completed.
Therefore, the correct answer is: B Plate
15) Diethyl ether is highly volatile liquid. Since it has a low boiling point at room temperature it can spread easily in the lab and possible danger of catching fire.
Hence, Diethyl ether is extremely flammable and as a result is a safety concern in the lab.
16) Natural dyes are hydrophilic in nature. Therefore, it can't be absorbed by synthetic fiber such as polyester or rayon.
They can easily adsorb by natural cotton.
hence, the answer is: False.
