(iii) Cl2 (iv) O2
Solution:
Covalent bonds are present in the given molecules.
(iii) Cl2 : An electron pair is shared by the two atoms of chlorine (Cl2). Covalent bonding is the term for this. Atoms can fill their valence shells by sharing electrons through covalent bond formation, resulting in a noble gas configuration.
(iv) O2 : Because each oxygen atom is two electrons short of having a complete outer shell, it shares two of its electrons with the other atom, resulting in both oxygen atoms having a complete outer shell. The strong O=O oxygen–oxygen double covalent bond holds the oxygen molecule together by sharing electrons.
