Chemistry
1 answer:
VashaNatasha [74]3 years ago
3 0

Explanation:

Scientific method basically minimizes the bias and prejudice in the experimenter. It provides an standardized approach for an experiment. It is a logical approach to seek knowledge that involves forming and testing a hypothesis. There is not a single way to list the steps in scientific method, but the ultimate goal is to gather data that will check the validity of an experiment.

Let’s say you have 3 UV active spots in the crude material and co-spot TLC plate. One has the same Rf value as the starting mate
Troyanec [42]

Answer:

Answer: (1R,2S) / (1S, 2R) , (1R,2R) / (1S, 2S)  

Explanation:

Sodium borohydride reduction of benzoin will give four possible stereo isomers out of which are (1R,2S) - (1S, 2R) isomers and (1R,2R) - (1S, 2S) isomers which are known as enantiomers.

In general enantiomers show single spot in the TLC as they do not show any difference in Rf value (i.e) (1R,2S) - (1S, 2R) isomers show only one spot although they are two compounds and also (1R,2R) - (1S, 2S) isomers also show one spot. That is the reason why you are observing two spots in the TLC ( of reaction mixture) other than starting materilal.
