Respuesta :
The type of reaction is represented by the generic equation AB + CD -> AD + CB is double replacement. The rest of the choices do not answer the question above.
Answer : Option D) Double replacement
Explanation : Double displacement or replacement reactions are those in which the two reactant molecules exchange the cations and anions between them and give a new product.
So, in this case when the reaction is AB + CD → AD + CB
Here, both the species of reactant compound molecule went replacement with the adjacent cation and anion group and formed a new compound or product. Therefore, this can be called as double replacement reaction.
