Which type of reaction would NOT be considered a redox reaction as well?

Question

a
Single replacement reactions
b
Double replacement reactions
c
Combination or synthesis reaction
d
Decomposition reactions

Answer 1

b
Double replacement reactions

Double replacement reactions typically involve the exchange of ions between two compounds without any change in the oxidation states of the elements involved. For a reaction to be classified as a redox reaction, there must be a change in the oxidation states of the elements due to the transfer of electrons. Since double replacement reactions do not involve electron transfer leading to a change in oxidation states, they are not considered redox reactions.
