MCAT BIO Domain 4: Organic Chemistry Welcome to your MCAT BIO Domain 4: Organic Chemistry 1. MCAT Bio: Organic Chemistry Which reagent is most suitable for converting an alcohol into a good leaving group? NaOH PBr? NaH H?O None 2. MCAT Bio: Organic Chemistry During a Fischer esterification reaction, what role does the acid catalyst play? Provides a source of protons to generate the good leaving group Acts as a nucleophile Supplies electrons for the formation of the ester bond Functions as a reducing agent None 3. MCAT Bio: Organic Chemistry In an SN2 reaction, what is the effect of increasing the steric hindrance at the carbon undergoing substitution? Increases the reaction rate Decreases the reaction rate No effect on the reaction rate Changes the mechanism to SN1 None 4. MCAT Bio: Organic Chemistry Which compound would exhibit the highest degree of resonance stabilization? Benzene Cyclohexane 1,3-butadiene Ethylene None 5. MCAT Bio: Organic Chemistry What is the major organic product of the reaction between 2-methylpropene and hydrochloric acid? 2-chloro-2-methylpropane 2-chloro-2-methylpropene 1-chloro-2-methylpropane 2-methylpropene None 6. MCAT Bio: Organic Chemistry In the context of molecular orbital theory, which molecule has the lowest bond order? O? N? C? B? None 7. MCAT Bio: Organic Chemistry What type of isomerism is exhibited by compounds having the same molecular formula, differing only in the spatial orientation of atoms around a double bond? Chain isomerism Position isomerism Functional group isomerism Geometric isomerism None 8. MCAT Bio: Organic Chemistry Which mechanism describes the addition of water to an alkyne to form a ketone? Hydroboration-oxidation Oxymercuration-demercuration Acid-catalyzed hydration Catalytic hydrogenation None 9. MCAT Bio: Organic Chemistry In a Diels-Alder reaction, what type of components react together? An alkene and an alkyne A diene and a dienophile Two alkenes An alkene and a carbonyl compound None 10. MCAT Bio: Organic Chemistry Which statement best describes the outcome of a nucleophilic aromatic substitution reaction? A substituent on an aromatic ring is replaced by a nucleophile without disrupting the aromaticity. A nucleophile adds to an aromatic ring, creating a new aromatic compound. The nucleophile replaces a hydrogen atom directly attached to the aromatic ring. An aromatic compound is transformed into a non-aromatic compound through the addition of a nucleophile.
