Six atoms of the peptide bond group are always planar due to the ____________. Dipole of amide linkage of a peptide bond is due
to partially ___________charged carbonyl oxygen and partially ___________ charged amide nitrogen. Select one: a. phi and psi angles; negatively; positively b. trans position between amide hydrogen and carbonyl oxygen; positively; negatively c. resonance structure; negatively; positively d. resonance structure; positively; negatively e. trans position between amide hydrogen and carbonyl oxygen; negatively; positively
Resonance because the lone pairs undergo resonance due tothe partial bond relationship BTW Carbon - Nitrogen bond so the bond length shortens making the six atoms of peptide bond planar
And positive because The dipole of amide linkage of a peptide bond is as a result of the partially positively charged carbonyl oxygen and partially positively charged amide oxygen.
And the negative because The carboxylic acid group -COOH is an acid donates H+ and -NH2 being a base is H+ so causes a partial negative charge to develop on -COO(-) and partial positive charge to develop on -NH3(+).l
<span>Mendeleev's periodic table was in error because when the elements were arranged by mass it resulted in several elements being placed in groups of elements with differing properties.</span>
