What is the correct assignment of the names of the following aromatic heterocycles? Select one: a. I = pyrimidine. Il =pyrrole: Ili = furan. b. l = pyrimidine: Il = pyrrole: lll = tetrahydrofuran. c. 1 = pyridine: il = pyrimidine: lll = furan. d. 1 = pyridine: Il = pyrrole; ll. = furan.
what is the correct assignment of the names of the following aromatic heterocycles What is the correct assignment of the names of the following aromatic heterocycles? O I = pyridine; Il = pyrimidine; III = furan, O I = pyrimidine; Il =pyrrole; III = furan. 0 1 = pyridine; Il = pyrrole; Ill = furan. 0 1 = pyrimidine; Il = pyrrole; 111 = tetrahydrofuran,
Aromatic heterocycles also undergo electrophilic aromatic substitution reactions. When furan is treated with an electrophile, the electrophile is installed only at the C-2 position. Explain why this reaction occurs only at the C-2 position, rather than the C-3 positions.(explain in words and resonance structures) Question 2 (10 pts). Aromatic heterocycles can undergo EAS reactions. When furan (below) is treated with an electrophile, an EAS reaction occurs in which the electrophile is installed only at carbon 2, not carbon 3. Explain...
