When it is treated with sodium ethoxide in deuterated ethanol (C2H5OD), 1,3-cyclopentadiene exchanges all of its hydrogens for deuterium. Draw a structure for the reactive intermediate that forms in this reaction in its hydrogen form.

#7 how does the structure of amino acids allow them to form a polypeptide? each amino acid has an amino group and a carboxyl group. each amino acid has a hydrogen atom and a carboxyl group. each amino acid has a carboxyl group and an r group. each amino acid has an r group and a hydrogen atom.
