Compare the data for the melting points of pure urea and pure cinnamic acid from the data provided for you in the postlab with the literature melting point. Which of the following best describes the comparison between the experimental and literature melting points for urea and cinnamic acid?
A) The experimental melting points for both urea and cinnamic acid match closely with the literature values.
B) The experimental melting point for urea matches closely with the literature value, but the experimental melting point for cinnamic acid deviates significantly from the literature value.
C) The experimental melting point for cinnamic acid matches closely with the literature value, but the experimental melting point for urea deviates significantly from the literature value.
D) Both experimental melting points for urea and cinnamic acid deviate significantly from the literature values.
