what could be the possible
structure of this nmr? The unknown compounds has melting point
range of 93-96 degree Celsius
Homework Answers
From the NMR it seems it has 5-aromatic H-atom and since there is no other peak so it might have groups without H-atom or replaceable H-atom and hence not present.
Now melting point won't help much. Get an 13C NMR spectrum and HRMS or GCMS to know the molecular mass. Otherwise you can't say anything with confirmation.
