Question

vii)
if the "C NMR spectrum of compound 'A contains two signals and PH NMR spectrum contain only
one signal, then what is the name of compound A?
a) Ethanol​

Answer 1

Explanation:

The ring carbon atom that is bonded to the propyl substituent will have different chemical shift. In propyl substituent, there are three non-equivalent carbon atoms. So, there are seven non-equivalent carbon atoms in propylbenzene. . Therefore, this compound gives seven signals in 13C NMR.
