Explanation: For A two-component mixture containing 1-octene and 1, 4-dimethylbenzene with acetone.
Error----- The retention factor (Rf) is 0.95 and the two spots are coming simultaneously together producing only one spot indicating that that the choice of solvent we have used is too polar. The compounds are interacting rapidly with the very polar solvent and have very low interaction with the stationary phase. than the mobile phase.
Solution:-----, We will need to try other low polar solvent that can allow two spots to be formed on the TLC plate eg is the use of different percentage s of hexane in ethyl acetate ether 10% or 20%.
Answer:
C. Precipitate the crystals as fast as possible
Explanation:
C. Precipitate the crystals as fast as possible
Precipitation if done fast , can lead to the formation of impure crystals , as impurities also get stuck inside the crystals. So it must be done slowly to obtain the pure crystals . Slower the crystals form , purer they are .
All the other options can lead to a successful recrystallization.
