Tardigrade Admin · Accepted Answer

Correct answer is (a) HI > HBr > HCl > HF

Q. Decreasing order of reactivity of HX in the reaction $RO H + H X \to RX + H_{2} O$

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

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

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

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

Correct answer is (a) $H I > H B r > H Cl > H F$
