A student was trying to determine the identity of an unknown compound. The melting point of the compound was 117-118oC. The student narrowed the possible compound down to the following: Compound Melting Point Range acetanilide 113-115oC fluorene 114-116oC mandelic acid 120-122oC A second student, doing the same experiment as above, found that their melting point was 100-108oC. What is wrong with the student’s melting point? Propose two reasons why the melting point could be incorrect.

Relationship between Affinity and Association & Dissociation Constant. Four proteins (A-D) all bind the same ligand (X), with different affinities. For protein A & B we know that they have a binding site for X with a Kd (dissociation constant) of 10-5and 10-8M, respectively. For protein C and D we know that they have a binding site for ligand X with a Ka (association constant) of 103and 105M, respectively. Which protein has the highest affinity for ligand X? Explain your reasoning.

According to the paper, F486 is a phenylalanine residue (i.e., an amino acid that is part of a chain that forms a protein) on SARS-CoV-2. It has an important interaction with ACE2 (best seen in Fig. 1(C) and Fig. 2(A)). Looking at this phenylalanine and the green residues surrounding it, which statement best describes the interaction that could be occurring? a) It forms a hydrogen bond with Y83. b) It forms a dipole-dipole interaction with M82. c) It forms London dispersion forces with surrounding residues. d) It encounters repulsions from surrounding residues.
