Video narration
Carbon ke yaugikon ka adhyay lagta hai, jaise sutron aur gunon ki lambi suchi yaad karni padegi. Lekin ise lego ke tukdon jaisa sochiye: alag tarah judkar vahi tukde kai sanrachnaen bana sakte hain. Carbon mein pehla karan hai tetravalency, yani ek carbon paramanu char sahsanyojak bandh bana sakta hai. Doosra hai catenation, carbon ka doosre carbon paramanuon se judna. Isse shrinkhalaen, shakhaen aur valay bante hain, isliye alag yogik sambhav hote hain. Yaad rakhiye: char bandh aur catenation, yahi vividhta ka karan hain.
