Interpretation Introduction

Interpretation:

The given set of spectra should be identified that it matches with the structure which contains ketone, carboxylic acid, alcohol, primary or secondary amine with it.

Concept Introduction:

IR spectral studies: It is a spectroscopic technique which is used to determine the functional groups present in the given compound sample by absorbing frequency in particular range with respect to the group present in the given sample.

Wavenumber: It is defined as the number of waves in one centimeter. The wavenumber indicates the location of each signal with respect to the functional group in the molecule and its unit is cm-1 .

Alcohol functional group: It refers to the functional group that contains one OH group bonded with the carbon atom in a molecule. The characteristic IR signal for OH group is broad signal at range of about 3200-3600 cm-1 .

Carboxylic acid functional group: It refers to the functional group that contains both carbonyl group ( C=O ) and alcohol group bonded to the same carbon. This functional group exhibits signal at 2200-3600 cm-1 for OH bond and 1700 cm-1 for C=O bond in carboxylic acid.

Ketone functional group: It is functional group that contains carbon double bonded with oxygen and remaining with other two carbon groups. It shows signals at 1700 cm-1 .

Primary and secondary amine:

It refers to the functional group that contains one nitrogen atom bonded to two hydrogen atoms and one carbon containing group and the secondary amine contains nitrogen bonded to one hydrogen atom and two carbon containing groups.
