Question

Identify the compound with a molecular formula $C_6{H}_{10}O$ that gives the following DEPT ¹³C NMR spectrum:

Short answer

The compound can be:

Step-by-step solution

DEPT spectrum

It is defined as Distortionless Enhancement by Polarization Transfer in which transfer of polarisation occurs from an excited nucleus to another. It is a type of double resonance program. In this, we can read the multiplicity directly by reducing CH coupling.

Identify compound from molecular formula

As per the given molecular formula we can find the number of carbon is 6 and hydrogen is 10 and the oxygen is present and the signal at 220 ppm shows the presence of the ketone having one methyl group and one CH group and three methylene groups.

Identify compound by DEPT spectra

As depicted by the DEPT the high-frequency signal is due to the methylene group and CH group showing these groups attached to carbonyl so the compound must be:
