What are vinylic and aryl halogen compounds? Explain with examples.

(N/A) Halogen compounds where the halogen is directly attached to an $sp^2$ hybridized carbon atom are classified as follows:
$(a)$ Vinylic halides $(C=C-X)$: Compounds in which the halogen atom is bonded to a carbon atom that is part of a carbon-carbon double bond ($sp^2$ hybridized carbon) are called vinylic halides.
Example: $CH_2=CHCl$ (Vinyl chloride).
$(b)$ Aryl halides $(Ar-X)$: Compounds in which the halogen atom is directly attached to a carbon atom of an aromatic ring ($sp^2$ hybridized carbon) are called aryl halides.
Example: $C_6H_5-X$ (e.g.,Chlorobenzene,$C_6H_5Cl$).
