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 \( CH_2 = CH - X \).
0.01 mole of an organic compound (X) containing 10% hydrogen, on complete combustion, produced 0.9 g H₂O. Molar mass of (X) is ___________g mol\(^{-1}\).
Consider the following sequence of reactions : 
Molar mass of the product formed (A) is ______ g mol\(^{-1}\).
Predict the major product $ P $ in the following sequence of reactions:
(i) HBr, benzoyl peroxide
(ii) KCN
(iii) Na(Hg), $C_{2}H_{5}OH$
