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 \( CH_2 = CH - X \).
For the thermal decomposition of \( N_2O_5(g) \) at constant volume, the following table can be formed, for the reaction mentioned below: \[ 2 N_2O_5(g) \rightarrow 2 N_2O_4(g) + O_2(g) \] Given: Rate constant for the reaction is \( 4.606 \times 10^{-2} \text{ s}^{-1} \).
