Question

Please label the and list all the main functional groups of 5-cholesten-3-one. Include stretching.

The first picture is the experimental IR and the second picture is the theoretical IR. please label all parts and list all major functional groups. Thank you.

Answer 1

1. Peaks at 2947 corresponds to sp3 CH stretch and at 1719 for C=O stretch and at 1467 for C-H bend.

2. Peak at 2966 cm-1 is due to Sp3 CH stretch and at 1721 for C=O stretch and at 1464 for C-H bend.
