Question

what is the general form of a single - replacement reaction?
a. ab + cd → ad + cb
b. ab + c → cb + a
c. a + b → ab
d. ab → a + b

Explanation:

In a single - replacement reaction, one element replaces another element in a compound. A more reactive element (C in this case) displaces an element (A) from its compound (AB) to form a new compound (CB) and a free element (A). Option A is a double - replacement reaction, option C is a combination reaction, and option D is a decomposition reaction.

Answer:

B. AB + C → CB + A
