Vedclass · Answer

(A) The acid strength is directly proportional to the acid dissociation constant $(K_a)$. The order of acid strength for hydrohalic acids is $HI > HBr > HCl > HF$.Comparing the given $K_a$ values:$HI: 3.2 	imes 10^9$ $(i)$$HBr: 1.0 	imes 10^9$ $(iv)$$HCl: 1.3 	imes 10^6$ $(iii)$$HF: 3.5 	imes 10^{-4}$ $(ii)$Therefore,the correct matching is $A-(i), B-(ii), C-(iii), D-(iv)$.

$A$. $HI$	$(i)$ $3.2 \times 10^9$
$B$. $HF$	$(ii)$ $3.5 \times 10^{-4}$
$C$. $HCl$	$(iii)$ $1.3 \times 10^6$
$D$. $HBr$	$(iv)$ $1.0 \times 10^9$

Match the given ionisation constant values with the corresponding acids.
$A$. $HI$ $(i)$ $3.2 \times 10^9$
$B$. $HF$ $(ii)$ $3.5 \times 10^{-4}$
$C$. $HCl$ $(iii)$ $1.3 \times 10^6$
$D$. $HBr$ $(iv)$ $1.0 \times 10^9$

The correct match is:
