Passage 1
Many alkenes can be hydrated simply by treatment with a strong acid in the
presence of water. The limitation of this method is that a carbocation is
generated along the mechanistic pathway, opening the door to rearrangements,
as shown in the sulfuric acid–catalyzed hydration of 3, 3-dimethylbut-1-ene here:
One workaround for this problem is the oxymercuration-demercuration
sequence, as shown here:
,Consider the hydration of 3,6-dimethylcyclohex-1-ene under two separate
conditions, for which four different alcohol products are proposed:
Q1. The most reasonable major hydration product of 3,6-dimethylcyclohex-1-ene
using water and sulfuric acid is:
A. Product A
B. Product B
C. Product C
D. Product D
Correct Answer Key: B
Q2. The most reasonable major hydration product of 3,6-dimethylcyclohex-1-ene
using oxymercuration-demercuration is:
A. Product A
B. Product B
C. Product C
D. Product D
Correct Answer Key: A

A. Product A
B. Product B
C. Product C
D. Product D
Correct Answer Key: B
Q4. Which of the following statements is MOST true for trans-3,6-
dimethylcyclohex1-ene?
A. There are two chiral centers and the molecule is chiral.
B. There are two chiral centers and the molecule is achiral.
C. There are no chiral centers and the molecule is chiral.
D. There are no chiral centers and the molecule is achiral.

Q6. A peregrine falcon of 9 N is a bird known for its ability to reach extremely high
speeds as it pursues prey. A bird in flight is subject to four forces: weight, drag,
, lift, and thrust. Which free body diagram accurately illustrates the direction of the
forces acting on the bird assuming the bird is moving at constant velocity?
Correct Answer Key: C
Q7. Blood is pumped from the heart at a rate of 5 L/min into the aorta of a typical
radius 1.2 cm. The velocity of blood as it enters the aorta is MOST nearly:
A. 9 cms \frac{cm}{s} scm
B. 12 cms \frac{cm}{s} scm
C. 18 cms \frac{cm}{s} scm
D. 32cms \frac{cm}{s} scm
Correct Answer Key: C
Q8. In response to a heart attack, the normal heart rhythm is restored by a
cardiac defibrillator, which transmits approximately 15 amperes of current
through the chest during a time interval of 7 milliseconds. The amount of charge
that flows during that time is:
