Expert Solution
Step 1

Calculation of double bond equivalence:

DBE=C+1-H2-X2+N2=10+1-102=6

Thus the given compound must have 6 double bonds or rings or their combination.

 

 

Step 2

Since there is a multiplet of 4 H at 7.1-7.3 ppm, thus the given compound must contain a benzene ring.

The ratio of protons is 2:2:2:4 or 1:1:1:2.

There are 6 signals of 'C' atom within the range of 136.64 to 126.82, thus the given compound must have:
