Question

Which type of reaction is represented by the generic equation AB + CD mc002-1.jpg AD + CB?

combustion

decomposition

single replacement

double replacement

Answer 1

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 2

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.
