Which solution has the highest boiling point? a) A solution formed by dissolving 0.75 mol of KCl in 1.00 kg of water.
b) A solution formed by dissolving 0.75 mol of glucose (C6H12O6) in 1.00 kg of water.
c) A solution formed by dissolving 0.75 mol of Ca(NO3)2 in 1.00 kg of water.
d) A solution formed by dissolving 0.75 mol of Na3PO4 in 1.00 kg of water.
e) All of the solutions described above have the same boiling point.

I know the answer is d but how would you find the highest b. p when they all have the same molality?

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.
