Alkenes
Explore the interactive model.
Model ko drag karke side aur top se dekho; steps ke saath methyl groups same ya opposite side freeze hote hain.
C=C ke across rotation restricted hai, isliye but-2-ene ke methyl groups ek nahi, do spatial arrangements mein lock ho sakte hain. Is 3D lab mein rigid double bond, exact 120-degree sp2 geometry aur methyl hydrogens ki tetrahedral arrangement dekhkar samajho ki har alkene carbon par do alag groups hone se cis-2-butene aur trans-2-butene kaise bante hain. Model ko ghoora aur plane guide ya H atoms toggle karke side aur top se structure check karo.
In but-2-ene, how are the two methyl groups arranged in the cis form?
