The reaction shown here can be best classified as a:

A combustion reaction
B combination reaction
C single-replacement reaction
D double-replacement reaction
Ans. D This question tests your understanding of the general classification of reactions. The reaction is clearly not a combustion reaction. Combustion reactions occur in the presence of oxygen and involve release of heat. There is no indication of that in the given reaction. You might be tempted to select Choice C since the given reaction is a replacement reaction, but double-replacement reaction best describes the given reaction. In the reaction, the iodine is replaced with the chlorine, and the chlorine is replaced with the iodine.
