what is the stretching frequency (in cm^-1) of the following carbonyl?\n1775\n1815\n1715
what is the stretching frequency (in cm^-1) of the following carbonyl?\n1775\n1815\n1715
Answer
Explanation:
Step1: Identify the carbonyl type
The given carbonyl is a cyclobutanone. Ring - strain affects carbonyl stretching frequencies. Cyclic ketones with smaller rings have higher - frequency carbonyl stretches due to increased ring - strain.
Step2: Recall typical stretching frequencies
For cyclobutanone, the carbonyl stretching frequency is around 1775 cm⁻¹ due to the significant ring - strain in the four - membered ring.
Answer:
1775
