Question

23. Furan reacts with ammonia in the
presence of alumina at 400° C to give :
(A) Pyridine
(B) Furfural
(C) Pyrrole
(D) Furoic acid​

Answer 1

Explanation:

Whereas simple cycloalkenes generally give addition reactions, 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

Answer:

The answer is Pyrrole.

Explanation:

Pyrrole is made by the catalytic reaction of furan with ammonia in the presence of alumina, molybdenum or vanadium oxide catalyst at the temperature of around 350-400°C. This react usually happens on the industrial scale.

Pyrrole is an organic compound with a ring structure. It contains four carbon atoms and one nitrogen atom.  Its molecular formula is C4H5N. Pyrrole molecules show anti-microbial, anti-cancer and anti-inflammatory properties.
