If the sample of the complex ion compound that you prepared had not thoroughly dried, but contained traces of water or ethanol would this make your value of x too high or too low? Or would it not affect your results at all? Explain.
the carbon-carbon bonds would be alternately long and short. However, to consider the structures as resonance contributors (or to connect them by a double-headed arrow) violates a basic principle of resonance theory.
