Enthalpy of neutralization

Question

Neutralization is the reaction between acid and base.It is highly exothermic.Enthalpy of neutralization is least for the reaction

Moderate

A

$HCl + NaOH$
B

$HCl + {NH}_{4} OH$
C

$HCN + NaOH$
D

$HCN + {NH}_{4} OH$

Solution

For a strong acid and strong base reaction, the net reaction is
$H^{+} + {OH}^{-} \to H_{2} O; ∆ H = - 57.3 kJ / mole$
Both $HCN and {NH}_{4} OH$ are weak electrolytes. They absorb energy for their ionization. Net heat liberated during the reaction is minimum.
