Question

furan reacts with ammonia in presence of alumina at 400 c to

Answer 1

Answer:

Whereas simple cycloalkenes generally give addition reaction aromatic compounds tend to react by substitution. The aromatic five-membered heterocycles all undergo electrophilic substitution with a general reactivity order : pyrrole > furan > thiophene > benzene

Answer 2

Pyrrole formed - furan react with ammonia in presence of alumina

Explanation:

• Pyrrole is made by the catalysis action of furan in the presence of alumina with ammonia , molybdenum or vanadium oxide used as catalyst at the temperature of about 350-400°C.
• Pyrrole is an organic compound that is heterocyclic with a ring structure and contains four carbon atoms and one nitrogen atom. It is colorless volatile liquid.
• Pyrrole molecular formula is C4H5N with molecules show anti-microbial, anti-cancer and anti-inflammatory properties.
• This type of reaction usually takes place on the industrial scale.
