1. The itchy rash that results from contact with poison ivy and poison oak is caused by a class of compound called "catechols" that are substituted with a long alkyl chain. The acid form of this organic compound, shown below, has a pK, of 8. The ionizable hydrogen is indicated in red. a) Draw this compound interacting with two different water molecules, with one water molecule serving as a hydrogen bond donor and the second serving as a hydrogen bond acceptor. Draw each water molecule as HOH and clearly indicate which atoms are interacting with the catechol. b) Draw the form of this compound as it would exist under physiological conditions, pH7.4
