Question

2. Which option denotes a double displacement reaction [___].
a) A +B+C
b) A +B-C
c) AC + BD AD + BC
d) AC + B → AB +C​

Answer 1

Answer:

option c

Explanation:

c) AC+ BD gives AD + BC

Because in the above reaction

• C is displaced with B
• D is displaced with A

Answer 2

(c).AC+BD→ AD+BC  is the correct answer, it denotes double displacement reaction.

Explanation:

A double displacement reaction can be defined as, the reaction in which the positive and negative ions of two ionic compounds exchange their places in order to form two new compounds. The general form of a (double-displacement) reaction is:

• AB+CD→AD+BC

In the above reaction,  A  and  C  are positively-charged cations, while  B  and  D  are negatively-charged anions. In order for a double displacement reaction to occur, one of the products is usually a solid precipitate, a gas, or a molecular compound such as water.

Hence,(c)AC+BD→ AD+BC is the correct answer.
