(a)
Interpretation:
Lewis dot structure of CF4 must be drawn.
Concept Introduction :
Lewis dot structure is the representation of a molecule with the valence electrons shown as dots.
(a)
Answer to Problem 5E
Lewis dot structure of CF4 is given below.
. 
Explanation of Solution
C has 4 valence electrons. F has 7 valence electrons. Thus one carbon is covalently bonded with 4 F atoms. There are three lone pairs of electrons on each F atom. Accordingly Lewis structure is shown as follows:

(c)
Answer to Problem 5E
Lewis dot structure of SiCl2H2 is given below.
.
Explanation of Solution
Si has 4 valence electrons, Cl has 7 valence electrons and H has one valence electron. Thus one carbon is covalently bonded with 2 H atoms and 2 Cl atoms. There are three lone pairs of electrons on Cl atom. Accordingly Lewis structure is shown as follows:
(d)
Interpretation:
Lewis dot structure of CH3OH must be drawn.
Concept Introduction :
Lewis dot structure is the representation of a molecule with the valence electrons shown as dots.
(d)
Answer to Problem 5E
Lewis dot structure of CH3OH is given below:
.
Explanation of Solution
C has 4 valence electrons. O has 6 valence electrons. H has one valence electron. Thus one carbon is covalently bonded with 3 H atoms and 1 O atom. The O atom is bonded with central carbon atom and one hydrogen atom. There are 2 lone pairs of electrons on O atom. Accordingly, Lewis structure is shown as follows:
(e)
Interpretation:

(e)
Answer to Problem 5E
Lewis dot structure of HOCl is given below.
.
Explanation of Solution
O has 6 valence electrons, Cl has 7valence electrons and H has one valence electron. Thus one central O is covalently bonded with 1 H atoms and 1 Cl atom. There are 2 lone pairs of electrons on O atom and 3 lone pairs of electrons on Cl atom. Accordingly Lewis structure is shown as follows
(f)
Interpretation:
Lewis dot structure of CH3NH2 must be drawn.
Concept Introduction :
Lewis dot structure is the representation of a molecule with the valence electrons shown as dots.
(f)
Answer to Problem 5E
Lewis dot structure of CH3NH2 is given below.
.
Explanation of Solution
C has 4 valence electrons, N has 5 valence electrons and H has one valence electron. Thus one central C is covalently bonded with 3 H atoms and 1 N atom. N atom is covalently bonded with central C atom and two hydrogen atoms. There are 2 lone pairs of electrons on N atom. Accordingly Lewis structure is shown as follows:
