They have been used as plastic stabilizers and as pesticides or fungicides. One method used to prepare simple tetraalkylstannanes is the controlled direct reaction of liquid tin(IV) chloride with highly reactive trialkylaluminum compounds, such as liquid triethylaluminum (Al(CzHs)3). 3SnCl4 + 4Al(C2H5)3 → 3Sn(C2H5)4 + 4AlCl3 In one experiment, 0.160 L of SnCl4 (d= 2.226 g/mL) was treated with 0.346 L of triethylaluminum (Al(C2H5)3); d = 0.835 g/mL). What is the theoretical yield in this experiment (mass of tetraethylstannane, Sn(C2H5)4)?
