Draw three resonance structures for nitrosyl chloride (NOCl) and assign formal charges to each atom. (Nitrogen is the central atom) A) Which resonance structure is favored by formal charge considerations & why? B) For the favored resonance structure, what is the electron and molecular geometry around the nitrogen atom? What is the bond angle?

Please please help!! Consider three dipeptides: i) S-G-K ii) I-K-Y iii) V-P-T Draw peptide (i) illustrating the resonance structures that limit free rotation around the peptide bonds on each side of the center amino acid Show which bonds have the angles we call phi () and psi (). This peptide represents a normal peptide on the Ramachandran diagram. Draw peptides (ii) and (iii) and label them with phi () and psi () (don’t do the resonance structures again). Which...
