Answer:
1710 cm^-1
Explanation:
The Infrared spectrum of the starting material will have a peak present at 1710 cm^-1. this is because
2-methylcyclohexanone has a ketone group (C=O) which will be reduced to an alcohol group (O-H), in the product i.e. (2-methylcyclohexanol). therefore the peak for the stretching vibration of the ketone carbonyl (C=O) is present only in the starting material only .and The peak for the stretching is at 1710 cm^-1
