Ultraviolet spectroscopy of often used to monitor the amount of a protein in a sample, the amount of protein is correlated with the absorbance at 280nm. Explain which of the following amino acids you expect to have an absorption at 280nm, (the carbonyl groups of the peptide [amide] bond of the protein do not absorb at thiswavelength).

Use resonance to explain thisobservationCalculate the formal charges on all of the atoms except hydrogen’s, in thesecompounds:A covalent ion can also have polar bonds. Consider the ammonium caution. I low arc its bonds polarized? Do you think that the N of the ammonium caution is more or less ‘electro negative’ than the N of ammonia (NH3)? ...Explain why the ultraviolet spectrum of one of these dienes has its maximum absorption at a longer wavelength than that of the other.
