Question

2/7
which of the following is an example of a nonpolar covalent bond?
hydrochloric acid (hcl) oxygen (o2)
sodium chloride (nacl) water (h2o)

Explanation:

• Non - polar covalent bonds occur when two atoms of the same element share electrons equally. In \(O_2\), two oxygen atoms share electrons equally.
• In \(HCl\), there is a polar covalent bond because hydrogen and chlorine have different electronegativities.
• \(NaCl\) has an ionic bond (transfer of electrons from \(Na\) to \(Cl\)).
• In \(H_2O\), there are polar covalent bonds (difference in electronegativity between \(H\) and \(O\)).

Answer:

Oxygen (\(O_2\))
