Chapter 13: Q54P (page 612)

The IR spectrum of a compound with molecular formula C5H8O is shown below. Identify the compound.

Short Answer

Expert verified

The compound can be:

Step by step solution

01

Degree of unsaturation (DOU)

It is defined as method of calculation or number of rings and double bond from the molecular formula of the compound so the degree of un saturation is 4.

02

Identify compound from IR spectra

As the presence of the longest peak shows the presence of the double bond character asper formula can be

03

Identify a functional group of the compound from IR spectra

As the wavelength of phenate is longer than the wavelength of phenol and the longest wavelength show pH=11

But as per the peaks in the left region shows the presence of the aromatic ring so the possibility of the compound is
