a.

b.

c.

Short Answer

Expert verified

Answer

Number ofC13NMR signals

  1. 6 signals
  2. 7 signals
  3. 4 signals

Step by step solution

01

C13 NMR

The C13has an odd number of neutrons and hence exhibits the NMR phenomenon. It is used to understand the backbone of an organic molecule, to identify the number of equivalent carbon and types of carbons.

02

Number of  C13 NMR signal

a. Six types of carbons are present in the structure which are represented as:

Equivalent carbon in structures

Therefore, the compound gives 6 signals.

b. All the carbons in the structure are non-equivalent because of different chemical environment.

Structure with no equivalent carbon

Therefore, the compound gives 7 signals.

c. There are four sets of equivalent carbons which are represented as:

Equivalent carbon in structures

Therefore, the compound gives 4 signals.
