1. Open-ended: Describe the mechanism of the SN1 reaction and
how it differs from SN2.
Answer: The SN1 reaction involves a two-step mechanism where
the leaving group departs before the nucleophile attacks, forming
a carbocation intermediate. This differs from SN2, which is a onestep process where the nucleophile attacks simultaneously as the
leaving group leaves, without forming a carbocation.
2. Fill-in-the-blank: Infrared spectroscopy measures the
absorption of infrared light, which causes molecular _____ to
change.
Answer: Vibrations
3. True/False: In NMR spectroscopy, the chemical shift of a
hydrogen atom is directly proportional to the electron density
around it.
Answer: False. The chemical shift is inversely proportional to the
electron density around the hydrogen atom.
4. Multiple-choice: Which of the following is not a type of UVVis spectroscopy transition?
A) σ to σ*
B) n to σ*
C) π to π*
D) d to f
Answer: D) d to f. This type of transition is not typically observed
in UV-Vis spectroscopy.
5. Open-ended: Explain the concept of chirality in organic
molecules and its significance in biochemistry.
Answer: Chirality refers to the geometric property of a molecule
having a non-superimposable mirror image. In biochemistry,
chirality is significant because it can affect the way a molecule
