question 20 what stretching frequencies (in cm⁻¹) are present in the structure below? 3300 2250
question 20 what stretching frequencies (in cm⁻¹) are present in the structure below? 3300 2250
Answer
Explanation:
Step1: Identify the functional - group
The structure contains a nitrile group ($-C\equiv N$).
Step2: Recall stretching frequency of nitrile
The stretching frequency of a nitrile ($-C\equiv N$) group is around 2200 - 2250 $cm^{-1}$.
Answer:
2250
