MCAT Organic ChemistryWhat are the four rules for writing resonance structures? - correct answer 1. Atoms must not be moved. Only electrons. 2. All resonance atoms must lie in the same plane. 3. Only valid Lewis structures are allowed. 4 . The number of unpaired electrons must remain constant. What are the two conditions for resonance? - correct answer 1. An atom must have a P orbital or a lone pair of electrons. 2. It must be single bonded to an atom that has a double or triple b...

ACS BIOCHEMISTRY EXAM QUESTION WITH COMPLETE SOLUTIONS LATEST 2024. Henderson-Hasselbach Equation - CORRECT ANSWER - pH = pKa + log ([A-] / [HA]) FMOC Chemical Synthesis - CORRECT ANSWER - Used in synthesis of a growing amino acid chain to a polystyrene bead. FMOC is used as a protecting group on the Nterminus. Salting Out (Purification) - CORRECT ANSWER - Changes soluble protein to solid precipitate. Protein precipitates when the charges on the protein match the charges in the solution....
