Hello I am working on question # 3 practice critical thinking question I think the answer would be the second dot to be a byproduct or smudgeness from developing chamber. I am not really sure how to answer this question any help greatly appreciated.

#2: Ying is running a recrystallization reaction. and is patiently waiting for her hot flask to cool toroom temperature. However. her impatient lab partner Jiana worries that they will run out of timeto complete the lab. and quickly places the flask in an ice bath. A large amount of solid productappears in the flask. allowing Ying and Jiana to obtain a good percent yield of the product.However, when the melting point of the product was taken. it had dropped far below the expectedmelting point of their product. How do you explain their result? #3: Cassandra and Arash have successfully completed Experiment #2. After running a meltingpoint analysis on their product. they believe their product is the result of reacting 4-methoxyphenol. However, when they run their standard of the 4-methoxyphenol product (on theleft-hand side of the plate) and their experimental product (on the right-hand side of the plate).they obtain the following result. — Cassandra believes that the second dot signifies some of the 4—methoxyphenol reactantfrom the reaction that had not gone to completion (or reacted completely). - Arash believes that the second dot can be explained by stockroom error. suggesting thatthe stockroom could have mixed the 4-methoxyphenol and the 4-chlorophenol solutionswith one another. therefore producing two distinct product. What would be the appropriate measures to take to determine whether Cassandra or Arash’s error analysis is correct?
