Answer 1

Answer #1

Yes, it is expected.

Since, Furan is also an aromatic compound.

With the aromatic ring current of benzene, it became possible in principle to determine the aromaticity of any molecule by measuring its ring current.

The ring currents in furan “did not differ significantly” from the benzene ring current.

Hence, the peaks corresponding to the Hs on the furan ring appear at chemical shifts that are typical for benzene Hs.
