what stretching frequencies (in cm⁻¹) are present in the structure below?\n2000\nnone of these\nall of these\n1715
Answer
Explanation:
Step1: Identify functional groups
The structure contains an ester functional - group (R - CO - O - R').
Step2: Recall ester C=O stretching frequency
The C=O stretching frequency of an ester is typically around 1735 - 1750 cm⁻¹ for aliphatic esters and 1715 - 1730 cm⁻¹ for aromatic esters. In this case, considering the structure, the C=O stretching frequency is likely around 1715 cm⁻¹.
Answer:
1715
