SOLVED: Question 22: The following scheme shows the oxidation of thiophene to thiophene sulfone:[0]ThiopheneThiophene sulfone(a) Explain why thiophene is considered aromatic.(b) Draw an aromatic system diagram of thiophene that clearly indicates the orbitals in which the two pairs of non-bonding valence electrons on sulfur reside. Also, explain whether thiophene can be oxidized to the corresponding sultone with reference to the hybridization of the sulfur atom and the availability of non-bonding

SOLVED: 3-Thiophene (C4H4S) is a fairly volatile liquid with a vapor pressure of 40.0 torr at 12.5Â°C, and its normal boiling point is 84.0Â°C. Calculate an estimate of thiophene's enthalpy of vaporization in kJ/mol.A mixture of cyclopropane gas (C3H6) and oxygen (O2) in a 1.00 to 4.00 mole ratio is used as an anesthetic. What mass of cyclopropane gas is present in a 2.00 L flask at 23.5Â°C if the total pressure of the oxygen and propane is 1.00 atm? (The molar mass of C3H6 is 42.08 g/mol.)

SOLVED: Look up the structures of thiophene and furan. After dealing with pyrrole above, you should now know whether or not the lone pairs can be part of a continuously overlapping set of p-orbitals (if not, draw the structures and place the lone pairs in space using VSEPR...are they above/below the ring plane?). But wait! The heteroatoms here each have two lone pairs. Only one pair overlaps (to justify this, try drawing a resonance structure with both overlapping). Much experimental evidence in
