what stretching frequencies (in cm⁻¹) are present in the structure below?\nall of these\n1745\nnone of these\n1685
Answer
Explanation:
Step1: Identify the functional - group
The structure is an ester. The carbon - oxygen double - bond ($C=O$) in esters typically has a stretching frequency around 1745 cm⁻¹.
Step2: Analyze the given options
We compare the typical stretching frequency of the $C=O$ in esters with the given options.
Answer:
1745
