Transcript text: Question 4
What stretching frequencies (in $\mathrm{cm}^{-1}$ ) are present in the structure below?
1745
1800
1715
Solution
Solution Steps
Step 1: Identify the functional group
The given structure contains a carbonyl group (C=O) bonded to a chlorine atom and a cyclohexyl group. This functional group is called an acid chloride.
Step 2: Determine the typical stretching frequency of acid chlorides
Acid chlorides (RCOCl) have a characteristic C=O stretching frequency in the range of 1780-1820 cm⁻¹.
Step 3: Choose the closest value
Among the given options, 1800 cm⁻¹ falls within the typical range for acid chlorides.
