Among the following, the vinylic halide is ____________.

Vinylic halides are compounds in which the halogen \( (X) \) is directly bonded to a doubly bonded carbon (alkene carbon).
- Contains a halogen on a saturated carbon, making it an alkyl halide.
- (c) Represents an aryl halide (halogen attached to a benzene ring).
- (d) Contains a halogen on an allylic position, making it an allylic halide.
- Contains a halogen directly bonded to a doubly bonded carbon, making it a vinylic halide.
Thus, the correct answer is \( CH_2 = CH - X \).
Which one of the following graphs accurately represents the plot of partial pressure of CS₂ vs its mole fraction in a mixture of acetone and CS₂ at constant temperature?
