Answer : The incorrect option is, (d)
Explanation :
According to the Bronsted Lowry concept, Bronsted Lowry-acid is a substance that donates one or more hydrogen ion in a reaction and Bronsted Lowry-base is a substance that accepts one or more hydrogen ion in a reaction.
Or we can say that, conjugate acid is proton donor and conjugate base is proton acceptor.
(a) The equilibrium reaction will be,
In this reaction, is an acid that donate a proton or hydrogen to
base and it forms
and
are conjugate base and acid respectively.
In this reaction, are act as a conjugate acid-base.
(b) The equilibrium reaction will be,
In this reaction, is an acid that donate a proton or hydrogen to
base and it forms
and
are conjugate base and acid respectively.
In this reaction, are act as a conjugate acid-base.
(c) The equilibrium reaction will be,
In this reaction, is an acid that donate a proton or hydrogen to
In this reaction, are act as a conjugate acid-base.
(d) The equilibrium reaction will be,
In this reaction, is an acid that donate a proton or hydrogen to
base and it forms
and
are conjugate base and acid respectively.
In this reaction, are act as a conjugate acid-base.
(e) The equilibrium reaction will be,
In this reaction, is an acid that donate a proton or hydrogen to
base and it forms
In this reaction, are act as a conjugate acid-base.
From this we conclude that that, pairs of acids and conjugate bases is incorrectly labeled or incorrectly matched.
Hence, the incorrect option is, (d)
