(a)
Interpretation: The Lewis dot structure and structural formula of SiF4 needs to be drawn.
Concept Introduction: Valence electrons are involved in covalent bonding where sharing of electrons takes place.
(a)

Explanation of Solution
Lewis dot structure can be drawn with the help of valence electrons. Silicon has 4 valence electrons, Fluorine has 7 valence electrons. To complete the octet, Si will share 4 electrons, one electron each with fluorine.
Thus, the Lewis dot structure and structural formula of SiF4is represented as follows:

Interpretation: The Lewis dot structure and structural formula of CO2 needs to be drawn.
Concept Introduction: Valence electrons are involved in covalent bonding where sharing of electrons takes place.
(b)

Explanation of Solution
Lewis dot structure can be drawn with the help of valence electrons. Carbon has 4 valence electrons, oxygen has 6 valence electrons. To complete the octet, carbon will share 4 electrons, two electrons each with oxygen and form double covalent bond.
(c)
Interpretation: The Lewis dot structure and structural formula of CH4 needs to be drawn.
Concept Introduction: Valence electrons are involved in covalent bonding where sharing of electrons takes place.
(c)

Explanation of Solution
Lewis dot structure can be drawn with the help of valence electrons. Carbon has 4 valence electrons, hydrogen has one valence electrons. To complete the octet, carbon will share 4 electrons, one electron each with hydrogen and form single covalent bond.
(d)
Interpretation: The Lewis dot structure and structural formula of SF2 needs to be drawn.
Concept Introduction: Valence electrons are involved in covalent bonding where sharing of electrons takes place.
(d)

Explanation of Solution
Lewis dot structure can be drawn with the help of valence electrons. Sulphur has 6 valence electrons, Fluorine has 7 valence electrons. To complete the octet, sulphur will share 2 electrons, one electron each with fluorine and form single covalent bond.
(e)
Interpretation: The Lewis dot structure and structural formula of C2H4needs to be drawn.
Concept Introduction: Valence electrons are involved in covalent bonding where sharing of electrons takes place.
(e)

Explanation of Solution
Carbon has 4 valence electrons, hydrogen has one valence electrons. To complete the octet, carbon will share 4 electrons, one electron each with hydrogen and form single covalent bond.
When carbon shares two electrons with other carbon atom, it forms double bond.
(f)
Interpretation: The Lewis dot structure and structural formula of C2H2 needs to be drawn.
Concept Introduction: Valence electrons are involved in covalent bonding where sharing of electrons takes place.
(f)

Explanation of Solution
Carbon has 4 valence electrons, hydrogen has one valence electrons. To complete the octet, carbon will share 4 electrons, one electron each with hydrogen and form single covalent bond.
When carbon share three electrons with other carbon atom, it forms triple bond.
(g)
Interpretation: The Lewis dot structure and structural formula of C2H6needs to be drawn.
Concept Introduction: Valence electrons are involved in covalent bonding where sharing of electrons takes place.
(g)

Explanation of Solution
Carbon has 4 valence electrons, hydrogen has one valence electrons. To complete the octet, carbon will share 4 electrons, one electron each with hydrogen and form single covalent bond.

- Complete the reaction in the drawing area below by adding the major products to the right-hand side. If there won't be any products, because nothing will happen under these reaction conditions, check the box under the drawing area instead. Note: if the products contain one or more pairs of enantiomers, don't worry about drawing each enantiomer with dash and wedge bonds. Just draw one molecule to represent each pair of enantiomers, using line bonds at the chiral center. More... No reaction. my ㄖˋ + 1. Na O Me Click and drag to start drawing a structure. 2.
