Question

Reactivity order of haloacid (HX) with ethyl alcohol is? (A) HF>HCl>HBr>HI (B) HCl>HBr>HF>HI (C) HBr>HCl>HI>HF (D) HI>HBr>HCl>HF

Tardigrade Admin · Accepted Answer

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

Q. Reactivity order of haloacid $(H X)$ with ethyl alcohol is?

$H F > H Cl > H B r > H I$

$H Cl > H B r > H F > H I$

$H B r > H Cl > H I > H F$

$H I > H B r > H Cl > H F$

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

$H I > H B r > H Cl > H F$
