Question

2. Write detailed study of vibrational frequencies of carboxyl compounds​

Answer 1

$\huge{\mathcal{\red{A}\green{N}\pink{S}\orange{W}\blue{E}\pink{R}}}$

All carbonyl compounds absorb in the region 1760-1665 cm-1 due to the stretching vibration of the C=O bond. This distinctive carbonyl band is particularly useful for diagnostic purposes because it has a characteristic high intensity and few other functional groups absorb in this region. Different carbonyl compounds absorb in narrow ranges within the general carbonyl region.
