Question

Q. 15. In Pyridine Electrophilic
Substitution occur almost exclusively
at
O a) position No. 2
O b) position No. 3
O c) position No. 2 and 3
O d) position No. 2, 3, 4 and 5​

Answer 1

Answer:

I think Answer D. position No. 2, 3, 4 and 5

Answer 2

In Pyridine Electrophilic substitution occurs almost exclusively at position no 3.

• Pyridine is a heterocyclic molecule having a formula C6H5N.
• Pyridine undergoes an electrophilic substitution reaction.
• Electrophile attaches to the 3 C, producing the most stable carbocation.
• When attached to the 3 C, the positive charge never ends on N atom.
