An organic chemistry student is experimentally determining the melting point of fluorenone. The experimental melting points are listed below from a to e. Which one should he discard so that he can say his data is precise?a. 83.5 °C.
b. 85.6 °C.
c. 83.6 °C.
d. 83.4 °C.
e. 83.3 °C.

During laboratory experiments, the precision of a result data covers the sameness of the data generated or results got each time the experiment is performed.

For the results to be seen as precise, the temperatures recorded during each experiment should be the same, or really close to each other.

Judging based on that, option B does not fit in as it is quite different from the other results by about 2 degrees Celsius. It also indicates that some errors may have occurred during the experiment.

To say his data is precise, he has to discard option b - 85.6 degrees Celsius.

The other temperatures recorded are close to each other. This would now make the data precise.
