Thiophene is a liquid compound of the elements C, H, and S . A sample of thiophene weighing 7.96 mg was burned in oxygen, giving 16.65 mg CO2. Another sample was subjected to a series of reactions that transformed all of the sulfur in the compound to barium sulfate. If 4.31 mg of thiophene gave 11.96 mg of barium sulfate, what is the empirical formula of thiophene? Its molecular weight is 84 amu. What is its molecular formula? | Numerade

SOLVED:Thiophene (fp=-38.3 ; bp=84.4^∘ C) is a sulfur-containing hydrocarbon sometimes used as a solvent in place of benzene. Combustion of a 2.348 g sample of thiophene produces 4.913 g CO2, 1.005 g H2 O, and 1.788 g SO2 . When a 0.867 g sample of thiophene is dissolved in 44.56 g of benzene (C6 H6), the freezing point is lowered by 1.183^∘ C . What is the molecular formula of thiophene?

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
