List the hydrogen halide acids in decreasing order of reactivity in the following reaction R - O H + H X → R X + H 2 O

Question

List the hydrogen halide acids in decreasing order of reactivity in the following reaction R - O H + H X → R X + H 2 O, HI > HBr > HCl > HF, HBr > HI > HCl > HF, HI > HCl > HBr > HF, HI > HF > HBr > HI

MARKS App · Accepted Answer

The relative rate follows same order as of acidity (HI > HBr > HCl > HF) and the nucliophilicity of their conjugate anion, X - ( I - > B r - > C l - > F - ) .
