Here are the Lewis structures for the given molecules, with the central atoms following the octet rule:
a. F₂:
Lewis structure: F-F
The fluorine atoms each have 7 valence electrons, and by sharing a pair of electrons, they both achieve the octet configuration.
b. O₂:
Lewis structure: O=O
The oxygen atoms each have 6 valence electrons, and by sharing two pairs of electrons, they both achieve the octet configuration.
c. CO:
Lewis structure: C=O
The carbon atom has 4 valence electrons, and the oxygen atom has 6 valence electrons. By sharing two pairs of electrons, they both achieve the octet configuration.
d. CH₄:
Lewis structure: H₃C-H
The carbon atom has 4 valence electrons, and by sharing a pair of electrons with each of the four hydrogen atoms, it achieves the octet configuration.
e. NH₃:
Lewis structure: H₃N
The nitrogen atom has 5 valence electrons, and by sharing a pair of electrons with each of the three hydrogen atoms, it achieves the octet configuration.
f. H₂O:
Lewis structure: H-O-H
The oxygen atom has 6 valence electrons, and by sharing a pair of electrons with each of the two hydrogen atoms, it achieves the octet configuration.
g. HF:
Lewis structure: H-F
The fluorine atom has 7 valence electrons, and by sharing a pair of electrons with the hydrogen atom, it achieves the octet configuration.
