Calculate the molar volume of saturated liquid and the molar volume of saturated vapor by the redlich / kwong equation for propane at 400c (313.15 k) where p sat = 13.71 bar and compare results with values found by suitable generalized correlations. (ans. for saturated liquid: z= 0.057; v = 108.1 cm3/mol; for saturated vapor: z= 0.789; v = 1499.2 cm3/mol)

Benzonitrile (c6h5cn) is reduced to two different products depending on the reducing agent used. treatment with lithium aluminum hydride followed by water forms k, which has a molecular ion in its mass spectrum at 107 and the following ir absorptions: 3373, 3290, 3062, 2920, and 1600 cm-1. treatment with a milder reducing agent forms l, which has a molecular ion in its mass spectrum at 106 and the following ir absorptions: 3086, 2850, 2820, 2736, 1703, and 1600 cm-1. l shows fragments in its mass spectrum at m/z = 105 and 77. propose structures for k and l and choose an explanation for how this could be concluded.
