what is the stretching frequency (in cm⁻¹) of the following carbonyl?\no\nh\nn\nh\n1685\n1745\n1715
Answer
Explanation:
Step1: Identify the carbonyl type
The given compound is a primary amide.
Step2: Recall amide carbonyl stretching frequency range
Primary amide carbonyls typically have stretching frequencies around 1680 - 1640 cm⁻¹ due to resonance and hydrogen - bonding effects.
Answer:
1685
