Question
The type of reaction which is not a redox reaction is
- Combustion
- Double displacement
- Combination
- All of these
Hint:
Double displacement reaction is not a redox reaction.
The correct answer is: Double displacement
The double displacement reaction is not a Redox reaction. This is because in this reaction two ionic species interact producing products and there is no loss or gain of electrons in a double displacement reaction.
