Q: In the conversion of a ketone to a hemiketal, which of the following changes in the infrared spectrum would indicate completion of the reaction?
A		Loss of a strong, sharp peak at 1700 cm-1 and appearance of broad peak around 3200 cm-1
B		Gain of a strong, sharp peak at 3200 cm-1 and loss of multiple smaller peaks at 2600, 1700, and 1400 cm-1
C		Gain of a strong, sharp peak at 2200 cm-1 and loss of a strong, sharp peak at 1700 cm-1
D		A change in the signature of the fingerprint region only
