The acidic strength of hydrides of halogens increases from top to bottom in VII group of periodic table. Hence HI is the strongest acid while HF is weakest one.

Q. The correct order of acidic strength is

$H F < H Cl < H B r < H I$

$H B r < H Cl < H I < H F$

$H Cl < H B r < H F < H I$

$H I < H B r < H Cl < H F$

The acidic strength of hydrides of halogens increases from top to bottom in VII group of periodic table. Hence $H I$ is the strongest acid while HF is weakest one.

Q. The correct order of acidic strength is

HF<HCl<HBr<HI

HBr<HCl<HI<HF

HCl<HBr<HF<HI
