@@SarojVidyapeethsir I have completed just first chapter of class 11 organic and just one is left, so I didn't understand(I think it's in ch-2😅) can you explain please.
It is in 'Haloalkanes and Haloarenes Class 12' chapter. The compound in which halogen is attached to doubly bonded carbon is known as Vinyl halide. Chlororthene is CH2=CHCl.
@@SarojVidyapeeth we use alkyl halide for halogen bonded with alkanes, then Why not alkenyl halide or something like that for double bond, I didn't like this vinyl LoL.
You can say it alkenyl halide. In alkenyl halide halogen may be attached to other carbon atoms.
Thnx sir good explanation 😊
Most welcome
