Which of the highlighted carbon-oxygen bonds absorbs at a higher wavenumber in an IR spectrum?
CH3CH2-OH or CH3CH__O
1. bond in the molecule on the right
2. bond in the molecule on the left

Respuesta :

Answer:

1. bond in the molecule on the right

Explanation:

CH3CH2-OH

The compound above is an alcohol due to the presence of the OH bond. The wave number of the C - O bond is given as; 1050-1150 cm^-1.

CH3CH__O

The compound above is an aldehyde due to the presence of the CHO bond. The wave number of the C = O  bond is given as; 1740-1720 cm^-1

Comparing both bonds, the C = O bond absorbs at a higher wave number.
