Which generalized equation represents a double displacement reaction?

a. a + bc → ac + b
b. ac +bd → ad + bc
c. ab → a + b

Option (B) is the correct answer.

Explanation:

A double displacement reaction is defined as the reaction in which there occurs interchange of both positive and negative ions of the reacting species.

For example,

Here, negative ion that is C and D interchange their places with each other resulting in the formation of two new compounds.

Therefore, we can conclude that the equation is the generalized equation which represents a double displacement reaction.

it is stable as it is in group 0 which have full outer shells of electrons
