Question

Enthalpy of neutralisation of HA,HB,HC,HC with KOH are - 12.8 kcal, - 12.9 kcal, - 11.9 kcal, - 11.3 kcal respectively. Which is strongest acid among the following :- (A) HA (B) HB (C) HC (D) HD

Heat of Ionisation of HA=13.6-12.8=0.8 HB=13.6-12.9=0.7 HC=13.6-11.9=1.7 HD=13.6-11.3=2.3

Q. Enthalpy of neutralisation of $H A, H B, H C, H C$ with $K O H$ are - $12.8$ kcal, - $12.9$ kcal, - $11.9$ kcal, - $11.3$ kcal respectively. Which is strongest acid among the following :-

$H A$

$H B$

$H C$

$HD$

Heat of Ionisation of
$H A = 13.6 - 12.8 = 0.8$
$H B = 13.6 - 12.9 = 0.7$
$H C = 13.6 - 11.9 = 1.7$
$HD = 13.6 - 11.3 = 2.3$

Q. Enthalpy of neutralisation of HA,HB,HC,HC with KOH are - 12.8 kcal, - 12.9 kcal, - 11.9 kcal, - 11.3 kcal respectively. Which is strongest acid among the following :-

HA

HB

HC

HD
