Question

Which substance contains bonds that involved the transfer of electrons from one atom to another?
(1) CO2 (3) KBr
(2) NH3 (4) Cl2

Answer 1

The transfer of electrons is an ionic bond, therefore, we need to determine which substance includes an ionic bond.

CO2, is a covalent bond, which is the sharing of electrons, not transfer.
KBr, is an ionic bond, because (k) loses an electron to bromine. 

So, our final answer is:-   (3) KBr
