Electrophilic Substitution of Pyrrole and Pyridine

[rsfreshie]

pyridine does not react with electrophiles, the ring must be activated first. N is electron withdrawing so decreases electron density in ring --> N lone pair is orthogonal to ring so cant be delocalised around ring. Ring must be activated with an electron donating group.

Student from India 🇮🇳 your lecture clear my doubts.

[sanjaymali]

thank you sir you clear my one dought ..love from India..

Hey man! I'm from Brazil and your videos are so great. I Always study looking at them, thanks man !

The problem with + on N in pyridine complex is not that it is on an electronegative atom, but that in the corresponding structure N violates the „octet rule“. Generally, there is NO problem with positive charge on an electronegative atom. That is just one of the few mistakes in the video.

wow i really like your videos so i always look for your lessons
its very clear and to the point thank you and pls make more videos

[cooldude]

Thanks sir, this explanation helped me in my Internal Assesment during CoronaTimes

[gowthamthevipre]

sir pyrole also have 4 resonnace structure(2nd position)and 3rd position it has ( r.s)

[HyunAYuchi]

Awesome lecture, thanks :)

May i ask if this would work the same way with Pyrazine, Pyrimidine, and Pyridazine ?
How about Pyrrole, Imidazole and Pyrazole ? Triazoles ? :)

Electrophilic substitution in pyrol is 2position but pyridine is 3 position comment

[legewright]

Divalent +ve charge on N is net destabilising. Pyrazole's non-azinyl nitrogen promotes EAS by accommodating +ve charge in tetravalent form. Your explanation is very misleading.

Thank you
Maita basa as I would say in my language

[nidabano]

Oh
Why pyrole structure is stablize in spite of having +ve charge on nitrogen

[devnayak]

sir can u upload examples behind electrophilic substitution of pyridine.
