Question

Estradiol is best described as which of the following? an alkyne an alkene an alkane an aromatic

Answer 1

an aromatic

Step-by-step explanation:

Estradiol has a fused ring structure with one benzene ring. The benzene ring has 6 pi electrons and a planar structure. Overall estradiol has a planar stricture and 6 pi electrons both of which make it aromatic. According to Huckel’s rule for aromaticity, estradiol has 4n +2 pi electrons, where n is 1.

Answer 2

As an aromatic.

Because it contains a ring with alternated dobule and single bonds where there are delocalized electrons. This ring has the same structure of the phenol (benzende with an OH radical).
