प्रश्न
Arrange the following hydrogen halides in order of their decreasing reactivity with propene.
विकल्प
HCl > HBr > HI
HBr > HI > HCl
HI > HBr > HCl
HCl > HI > HBr
उत्तर
HI > HBr > HCl
Explanation:
The decreasing order of reactivity of hydrogen halides with propene is HI > HBr > HCl. As the size of halogen increases, the strength of H – X bond decreases and hence, reactivity increases.
