SOLVED: 3-Thiophene (C4H4S) is a fairly volatile liquid with a vapor pressure of 40.0 torr at 12.5°C, and its normal boiling point is 84.0°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 23.5°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
