,300 Exam-Style Questions with Verified Answers
and Rationales
Qn 1. What is the relationship between (2R,3R)-2,3-dibromopentane and (2R,3S)-2,3-
dibromopentane?
A A. Identical compounds
B B. Enantiomers
C C. Diastereomers
D D. Constitutional isomers
Correct Answer: C. Diastereomers
Rationale: (2R,3R) and (2R,3S) are diastereomers because they have the same configuration
at one stereocenter and different at the other. They are not mirror images.
Why Wrong:
A. A: They are not identical.
B. B: They are not mirror images.
C. D: They have the same connectivity.
References: CHEM 233 Lesson 2 Materials; Organic Chemistry (McMurry); Organic
Chemistry (Wade); Clayden Organic Chemistry.
Qn 2. What is the relationship between enantiomers and diastereomers?
A A. Both are non-superimposable mirror images
B B. Enantiomers are mirror images; diastereomers are not
C C. Diastereomers are mirror images; enantiomers are not
D D. They are identical
Correct Answer: B. Enantiomers are mirror images; diastereomers are not
Rationale: Enantiomers are non-superimposable mirror images. Diastereomers are
stereoisomers that are not mirror images. They have different physical properties and can
be separated by standard methods.
Why Wrong:
A. A: Diastereomers are not mirror images.
B. C: Diastereomers are not mirror images.
, C. D: They are different types of stereoisomers.
References: CHEM 233 Lesson 2 Materials; Organic Chemistry (McMurry); Organic
Chemistry (Wade); Clayden Organic Chemistry.
Qn 3. What is the energy difference between anti and eclipsed conformations?
A A. Anti is higher in energy than eclipsed
B B. Anti is lower in energy than eclipsed
C C. They are equal in energy
D D. The difference is minimal
Correct Answer: B. Anti is lower in energy than eclipsed
Rationale: The anti conformation is lower in energy than the eclipsed conformation
because of reduced torsional strain. Eclipsed conformations have higher energy due to
eclipsing interactions.
Why Wrong:
A. A: Anti is lower in energy.
B. C: They are not equal in energy.
C. D: The energy difference is significant.
References: CHEM 233 Lesson 2 Materials; Organic Chemistry (McMurry); Organic
Chemistry (Wade); Clayden Organic Chemistry.
Qn 4. What is the energy difference between axial and equatorial methyl groups in
methylcyclohexane?
A A. Approximately 1.7 kcal/mol
B B. Approximately 0.5 kcal/mol
C C. Approximately 3.0 kcal/mol
D D. Approximately 5.0 kcal/mol
Correct Answer: A. Approximately 1.7 kcal/mol
Rationale: The energy difference between axial and equatorial methyl groups in
methylcyclohexane is approximately 1.7 kcal/mol (7.1 kJ/mol). The equatorial position is
favored due to reduced 1,3-diaxial steric interactions.
Why Wrong:
A. B: 0.5 kcal/mol is too low.
B. C: 3.0 kcal/mol is too high for a methyl group.
C. D: 5.0 kcal/mol is too high.
