CHEM 238

In order to determine whether the desired product type was produced in the Grignard Reaction, you obtained an IR spectrum. The main peak that should have been absent was at approximately:

a. 2400‐2580 cm‐1
b. 3200‐3600 cm‐1
c. 1700‐1720 cm‐1
d. 3010‐3100 cm‐1
e. Fingerprint Region

Answer: c. 1700-1720 cm-1 (carbonyl is replaced with alcohol group in grignard)
