Which reactions are single displacement reactions? 2nabr + caf2 → 2naf + cabr2 sno2 + 2h2 → sn + 2h2o 4na + o2 → 2na2o 2kclo3 → 2kcl + 3o2 2al + 6hcl → 2alcl3 + 3h2

Answer : The correct options are, and

Explanation :

Single displacement reaction : It is a type of chemical reaction in which the more reactive element displaces the less reactive element.

Option A reaction :

It is an example of double displacement reaction because in this reaction a positive cation and a negative anion of the two reactants exchange their places to form two new products.

Option B reaction :

It is an example of single displacement reaction.

Option C reaction :

It is an example of combination reaction because in this reaction two reactants react to give a single product.

Option D reaction :

It is an example of decomposition reaction because in this reaction a single reactant decomposes into two or more products.

Option E reaction :

It is an example of single displacement reaction because in this reaction the most react element, aluminium displaces the less reactive element, hydrogen.

Hence, the options B and E are single displacement reactions.
