@Criteria for aromaticity in non-benzoid compounds
Non-benzoid compounds ke liye bhi aromaticity ke liye kuch criteria hai.
Sabse pehla criterion ye hai ki, cyclic compound me delocalized pi electrons hona chahiye. Agar iske alawa cyclic compound ke pi electrons localized hote hai, to wo aromatic nahi hota hai.
Dusra criterion ye hai ki, cyclic compound planar hona chahiye. Agar cyclic compound ke atoms 3D space me arrange hote hai, to pi electrons ka delocalization nahi ho pata, aur wo aromatic nahi hota hai.
Teesra criterion ye hai ki, cyclic compound ka size chhota hona chahiye. Aromaticity ke liye, cyclic compound me electrons ka delocalization acche se hona zaroori hai. Agar cyclic compound ka size bahut bada hai, to electrons ka delocalization kam ho jata hai, aur wo aromatic nahi hota hai.

Ek aur criterion hai ki, non-benzoid compound me odd number of pi electrons hone chahiye. Agar cyclic compound ke pi electrons ki sankhya even hai, to wo anti-aromatic hota hai, jiska stability bahut kam hota hai. Odd number of pi electrons ka presence cyclic compound me, pi electrons ke delocalization ko facilitate karta hai, aur wo aromatic hota hai.
Non-benzoid compounds me bhi resonance aur conjugation ke concepts aromaticity ke liye important hai. Agar cyclic compound me delocalized pi electrons ka system bana ho, jisme adjacent atoms ke beech alternating single-double bond system ho, to wo conjugated hoga aur aromaticity ke liye eligible hoga.

Dono compounds me pi electrons ka delocalization hota hai, jisse aromaticity paida hoti hai.
Dono compounds me ring me alternate single aur double bonds hoti hai.
Dono compounds me 4n+2 pi electrons hone par aromaticity paida hoti hai, jaise ki benzenoid compounds me 6 pi electrons ke liye aur non-benzoid compounds me 5 aur 6 pi electrons ke liye.
Differences:
Benzenoid compounds me 6-membered ring hota hai, jabki non-benzoid compounds me 5-membered aur 6-membered ring dono ho sakte hai.
Benzenoid compounds me pi electrons ka delocalization hexagonal ring ke andar hota hai, lekin non-benzoid compounds me ring ke andar aur bahar dono pi electrons ka delocalization hota hai.
Benzenoid compounds me alternate single aur double bonds ke sequence fixed hota hai, jabki non-benzoid compounds me ye sequence different ho sakte hai.
Benzenoid compounds me aromaticity bahut stable hoti hai, jabki non-benzoid compounds me aromaticity ka stability kam ho sakti hai.
In sabhi similarities aur differences se pata chalta hai ki benzenoid aur non-benzoid compounds dono aromatic hote hai, lekin inki aromaticity me kuchh differences hai.
Ek aur difference hai ki non-benzoid compounds me heteroatoms (jaise nitrogen, oxygen, sulfur) present hote hai, jo benzenoid compounds me nahi hote hai. Ye heteroatoms pi electrons ka delocalization me participate karte hai aur aromaticity ko affect karte hai. Isliye non-benzoid compounds ki aromaticity benzenoid compounds se alag hoti hai.
Ek aur difference hai ki non-benzoid compounds me resonance energy aur pi electron density benzenoid compounds se kam hoti hai.

Iske alawa non-benzoid compounds me ring ke andar aur bahar ke atoms ke influence se bhi aromaticity aur stability affected ho sakte hai, jo benzenoid compounds me aisa nahi hota hai.
@Examples of compounds that exhibit both benzenoid and non-benzoid aromaticity
Kuchh compounds hote hai jo benzenoid aur non-benzoid aromaticity dono exhibit karte hai. In compounds ko “heteroaromatic compounds” bhi kaha jata hai. Kuchh examples niche diye gaye hai:
Pyridine: Pyridine ek heteroaromatic compound hai jisme 6-membered ring ke andar nitrogen atom present hai. Iske nitrogen atom ka lone pair pi electrons delocalization me participate karte hai, jisse non-benzoid aromaticity paida hoti hai.
Furane: Furane bhi ek heteroaromatic compound hai jisme 5-membered ring ke andar oxygen atom present hai. Iske oxygen atom ka lone pair pi electrons delocalization me participate karte hai, jisse non-benzoid aromaticity paida hoti hai.
Thiophene: Thiophene bhi ek heteroaromatic compound hai jisme 5-membered ring ke andar sulfur atom present hai. Iske sulfur atom ka lone pair pi electrons delocalization me participate karte hai, jisse non-benzoid aromaticity paida hoti hai.
In compounds me ring ke andar heteroatom ka presence ki wajah se non-benzoid aromaticity paida hoti hai, lekin ring ke structure ke karan benzenoid aromaticity bhi ho sakti hai.
Ye compounds benzenoid aromaticity bhi exhibit karte hai kyunki inke rings 6 pi electrons se bane hote hai aur unka planar structure hota hai, jaise benzenoid compounds me hota hai. Isliye in compounds me pi electrons delocalization benzenoid as well as non-benzoid mechanism se ho sakti hai.
Is tarah ke compounds ki example me se ek hai “pyrrole”, jisme 5-membered ring ke andar nitrogen atom hota hai. Isme nitrogen ka lone pair pi electrons delocalization me participate karte hai, jisse non-benzoid aromaticity paida hoti hai. Lekin pyrrole ka ring planar nahi hota hai, isliye benzenoid aromaticity bhi nahi hoti. Lekin pyrrole ka structure slightly non-planar hota hai, jisse non-benzoid aromaticity paida hoti hai.
Is tarah ke compounds me benzenoid aur non-benzoid aromaticity ki combination ki wajah se inki stability bhi benzenoid compounds se jyada hoti hai. In compounds ki properties aur reactions benzenoid compounds se alag hote hai aur inka study bhi interesting hota hai.
