what is the stretching frequency (in cm^-1) of the following carbonyl?\n\no\noh\n\n1775\n1685\nnone of the above\n1715\n1745
Answer
Explanation:
Step1: Identify the carbonyl type
The given compound is a benzoic - acid, which is a carboxylic acid. Carboxylic - acid carbonyls have characteristic stretching frequencies.
Step2: Recall the frequency range
The stretching frequency of a carboxylic - acid carbonyl is typically in the range of 1700 - 1720 $cm^{-1}$.
Answer:
D. 1715
