3. Methyl acetate is hydrolyzed at 25 oC in acidic environment. Aliquots of equal volume are removed and titrated with NaOH solution. The hydrolysis reaction is irreversible. The results are Time/s 339 1242 2745 4546 infinite Volume of base/ mL 26.34 27.80 29.70 31.81 39.81 Write the reaction of hydrolysis of methyl acetate. (3 pts.) Neglect the reverse reaction. Find the order of the hydrolysis reaction and the value of the rate constant at this temperature. (12 pts.) Total 15 pts.

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.
