| Specification: |
Behavior of Furan (CAS NO.110-00-9) is quite dissimilar to that of the more typical heterocyclic ethers such as tetrahydrofuran due to its aromaticity, .It is considerably more reactive than benzene in electrophilic substitution reactions, due to the electron-donating effects of the oxygen heteroatom. Examination of the resonance contributors shows the increased electron density of the ring, leading to increased rates of electrophilic substitution. |
