    Exercise 5.1.1:

    a) 0 b) 3- c) 3- d) 3+ e) 5+

    Exercise 5.1.2:

    a) O2 b) NO2- c) 2 e-

    Exercise 5.3.1:

    1. S: \(4 \times 2^{-} = 8^{-}\); Fe: \(2 \times 2^{+} + 2 \times 3^{+} = 10^{+}\); total \(= 2^{+}\)
    2. S: \(4 \times 2^{-} = 8^{-}\); Fe: \(1 \times 2^{+} + 2 \times 3^{+} = 8^{+}\); total \(= 0\)
    3. S: \(2 \times 2^{-} = 4^{-}\); Fe: \(2^{+} + 2^{+} = 5^{+}\); total \(=1^{+}\)

    d) As the Fe becomes more reduced, the N-N stretching frequency decreases. That's because the more electron density there is on the Fe, the more it is able to backbond to the N2 (N2 is a π acceptor).
