KCl...
Using the following reactions:
2KMnO4 + 5KNO2 + 3H2SO4 > 2MnS4 + #H2O + 5KNO3 + K2SO4
KClO3 + C12 H22O11 ---> KCl + H2o + CO2
K2Cr2O7 + SnCl2 + HCl ---> CrCl3 + SnCl4 + KCl + H2O
Mg + HCl > Mg Cl2 + H2
Fe + V2O3 ---> Fe2O3 + VO

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.
