Question

This is a THREE part question. Answer in the box below and ensure that you clearly label each section. Sodium nitrate (NaNO3) is a white solid compound that is soluble in water and forms nitrate, NO3- ions. On a rough sheet of paper, draw the Lewis structure of a nitrate ion. Following questions a-c are related to each other and will require you to refer to your Lewis structure. a) State the number of bonds and lone pairs involving the nitrogen atom in a nitrate anion. b) What is the formal charge on nitrogen in the nitrate anion? Explain briefly how to arrive at the answer. c) What is the average bond order of N-O bond in nitrate anion taking into account the resonance forms?
