Which type of reaction involves the transfer of electrons?

October 12, 2017

Which type of reaction involves the transfer of electrons?

(1) alpha decay
(2) double replacement

(3) neutralization
(4) oxidation-reduction 

 

 

Answer and Explanation:

Alpha decay is a type of nuclear reaction where the nucleus of parent atom breaks down and releases alpha particle( Helium atom) as well as a new atom. 

In a double replacement reaction, two ionic compounds come together  and switch their partners. Thus, they create two new ionic compounds.

In a neutralization reaction, an acid and base react together, or neutralize each other to create water and salt.

Finally, in oxidation-reduction reaction a transfer of electrons occurs. One element get oxidized (looses electrons, and another get reduced (gains electrons). Therefore, choice 4 is the correct answer.
