Is thiophene polar or nonpolar?
Thiophene is a monocyclic heteroarene that is furan in which the oxygen atom is replaced by a sulfur. It has a role as a non-polar solvent.
Which statement about thiophene is incorrect?
| Q. | Which statement about thiophene is incorrect? |
|---|---|
| A. | The S atom contributes two electrons to the n-system |
| B. | Thiophene is polar |
| C. | Thiophene is less reactive than pyrrole |
| D. | Thiophene is more reactive than furan |
Why is thiophene aromatic?
[Each atom can contribute a maximum of one orbital and two electrons towards aromaticity]. The other lone pair is in the plane of the ring, much like the lone pair on the nitrogen of pyridine, above. Therefore thiophene has six pi electrons total, which is a Huckel number, and thiophene is aromatic.
Which statement about thiophene is correct?
| Q. | Which statement about thiophene is incorrect? |
|---|---|
| B. | Thiophene is polar |
| C. | Thiophene is less reactive than pyrrole |
| D. | Thiophene is more reactive than furan |
| Answer» d. Thiophene is more reactive than furan |
Which statement is true about thiophene?
Is thiophene acidic or basic?
Pyrrol, furan or thiophene don’t have any bond pair electrons free to release which is why they shouldn’t be basic, but the lecturer of organic chemistry is saying that they are basic as they react with hydrochloric acid to form salts.
Is a furan aromatic?
Furan is an aromatic compound with the participation of the oxygen lone pair in the π-electron system to satisfy Hückel’s rule, 4n + 2 (n = 1) electrons. The compound is stable to heating up to about 550°C (depending also on heating time).
Why is thiophene more stable than furan?
Since N is less electronegative than O, it will be slightly more stable than O with that positive charge. Hence, pyrrole will be more aromatic than furan. Therefore, the aromaticity order should be: benzene > pyridine > pyrrole > furan > thiophene.
Why is thiophene more aromatic than pyrrole?
Raising the electronegative S in Thiophene will guide to the most significant growth in aromaticity. The aromaticity order in these heterocycles depends on the electronegativity of the heteroatom : 0>N>S Hence, the aromaticity is ordered as Thiophene > Pyrrole > Furan.
Which statement is incorrect about thiophene?
Which statement about thiophene is incorrect? Thiophene is polar. Thiophene is more reactive towards electrophiles than furan.
Why is thiophene more stable than pyrrole?
Answer: Since N is less electronegative than O, it will be slightly more stable than O with that positive charge. Hence, pyrrole will be more aromatic than furan. Therefore, according to me, the aromaticity order should be: benzene > pyridine > pyrrole > furan > thiophene.
Is thiophene more stable than furan?
In compared with pyrrole and furan thiophene is more stable.
How is thiophene different from furan and pyrrole?
The key difference between pyrrole furan and thiophene is that pyrrole contains a –NH group in a five-membered carbon ring and furan contains an oxygen atom in a five-membered carbon ring whereas thiophene contains a sulfur atom in a five-membered carbon ring.
Which is more stable thiophene or pyridine?
In compared with pyrrole and furan thiophene is more stable. Due to the fact nitrogen is much less electronegative than oxygen it will be barely greater stable than oxygen with that effective rate. Hence the basic strength order will be: pyridine > pyrrole > furan > thiophene.
