Q. The correct order of reactivity of hydrogen halides with ethyl alcohol is
A) HF > HCl > HBr > HI
B) HCl > HBr > HF > HI
C) HBr > HCl > HI >HF
D) HI > HBr > HCl > HF
Explanation
(d)
Among hydrogen halides, as the size of halide ion increases, its reactivity towards ethyl alcohol also increases. Thus, the order of reactivity of hydrogen halide is
HI > HBr > HCl > HF
