The correct option is B Vinyl chloride
Both vinyl chloride and chlorobenzene give no precipitate with alcoholic AgNO3 because both have chlorine atoms which are not reactive.
In Chlorobenzene, the chlorine atom is directly attached at the unsaturated carbon atom. In vinyl chloride also, the chlorine atom is directly attached to unsaturated carbon atom.
Hence, the action of alcoholic AgNO3 on chlorobenzene is similar to the action on vinyl chloride. Chlorine atoms are not reactive.
