Clonidine shown below is a top selling drug used to treat hypertension. Circle the most basic atom in clonidine and provide the conjugate acid if this atom was protonated and the two best resonance structures of the conjugate acid. CI N H N-H Clonidine 6. Put the below compounds in order of their acidity. Hint: Consider the pKa difference between CH3NO2 and acetone (CH3COCH3) when determining the order. A most acidic B D F E least > acidic
