dentify the statement that correctly interprets this TLC analysis of a recrystallized sample of acetaminophen produced following the procedure outlined in Experiment 5: The TLC of an individuals purified acetaminophen showed two spots. One spot had an Rf identical to that of pure acetaminophen. This spot was also larger and darker than the second spot. The Rf of the second spot was very close to the Rf of pure 4-aminophenol. a) The two spots evident in my TLC analysis indicate my sample is a mixture. Since each spot has an Rf value that is close to the Rf of one of the authentic materials tested, I can conclude my sample is a mixture of acetaminophen and 4-aminophenol. The large size of the spot with an Rf nearly identical to authentic acetaminophen indicates my sample is mostly 4-aminophenol. b)I can conclude from this evidence that my sample is a mixture of acetaminophen and 4-aminophenol because the Rf of each of the spots is nearly identical to one of the authentic sample Rf values. I cannot assess the purity of my acetaminophen. c)The two spots in my TLC analysis indicate my sample is not pure and the similarity of each spot's Rf to one of the authentic sample Rf's indicates my sample is a mixture of acetaminophen and 4-aminophenol. Since the spot with an Rf close to the Rf of authentic acetaminophen is larger and darker than the other spot, I can also conclude my sample contains a greater amount of acetaminophen than 4-aminophenol. d)The large spot with an Rf nearly identical to that of acetaminophen indicates that my sample mostly acetaminophen. e)The TLC indicates my sample is pure acetaminophen. f)I can conclude from this evidence that my sample is a mixture of acetaminophen and 4-aminophenol because the Rf of each of the spots is nearly identical to one of the authentic sample Rf values. I can also accurately estimate from the size and coloring of the larger spot that the purity of my sample is greater than 70% acetaminophen.
Identify the statement that correctly interprets this TLC analysis of a recrystallized sample of acetaminophen produced following the procedure outlined in Experiment 5: The TLC of an individuals purified acetaminophen showed two spots. One spot had an Rf identical to that of pure acetaminophen. This spot was also larger and darker than the second spot. The Rf of the second spot was very close to the Rf of pure 4-aminophenol.
a) The two spots evident in my TLC analysis indicate my sample is a mixture. Since each spot has an Rf value that is close to the Rf of one of the authentic materials tested, I can conclude my sample is a mixture of acetaminophen and 4-aminophenol. The large size of the spot with an Rf nearly identical to authentic acetaminophen indicates my sample is mostly 4-aminophenol.
b)I can conclude from this evidence that my sample is a mixture of acetaminophen and 4-aminophenol because the Rf of each of the spots is nearly identical to one of the authentic sample Rf values. I cannot assess the purity of my acetaminophen.
c)The two spots in my TLC analysis indicate my sample is not pure and the similarity of each spot's Rf to one of the authentic sample Rf's indicates my sample is a mixture of acetaminophen and 4-aminophenol.

d)The large spot with an Rf nearly identical to that of acetaminophen indicates that my sample mostly acetaminophen.
e)The TLC indicates my sample is pure acetaminophen.
f)I can conclude from this evidence that my sample is a mixture of acetaminophen and 4-aminophenol because the Rf of each of the spots is nearly identical to one of the authentic sample Rf values. I can also accurately estimate from the size and coloring of the larger spot that the purity of my sample is greater than 70% acetaminophen.
