Question on: JAMB Chemistry - 2022
The reactions below represent neutralization reactions, in which of them is the value of ΔH highest?
A
CH\(_3\)CH\(_2\)COOH + KOH → CH\(_3\)CH\(_2\)COOK + H\(_2\)O
B
NH\(_4\)OH + HCL → NH\(_4\) + H\(_2\)O
C
NaOH + HCL → NaCL + H\(_2\)O
D
CH\(_3\)COOH + NaOH → CH\(_3\)COONa + H\(_2\)O

Correct Option: C
Enthalpy changes of neutralization are always negative - heat is released from the reaction of an acid and an alkali.
Such enthalpy changes are smaller in magnitude compared to that between the reaction of strong acids and strong bases.
