Interpretation:
The Lewis dot structure of
Concept introduction:
Lewis structure represents the valence shell electrons in a compound. It shows the distribution of electrons around each atom in a molecule.
(a)
Explanation of Solution
Selenium is a 16th group element which has 6 valence electrons and fluorine is a 17th group element which has 7 valence electrons.
Total valence electrons = 6 + 2×7
= 6 + 14
= 20
Therefore; the total valence electron is 20.
The Lewis dot structure of SeF2 is shown below:

The Lewis dot structure of
Concept introduction:
Lewis structure represents the valence shell electrons in a compound. It shows the distribution of electrons around each atom in a molecule.
(b)
Explanation of Solution
Chlorine is a 17th group element which has 7 valence electrons and oxygen is a 16th group element which has 6 valence electrons.
Total valence electrons = 7 + 2×6 + 1
= 20
Therefore; the total valence electrons is 20.
The Lewis dot structure is shown below:
(c)
Interpretation:
The Lewis dot structure of
Concept introduction:
Lewis structure represents the valence shell electrons in a compound. It shows the distribution of electrons around each atom in a molecule.
(c)
Explanation of Solution
Phosphorus is a 15th group element which has 5 valence electrons and oxygen is a 16th group element which has 6 valence electrons.
The total number of valence electrons = 5 + 3(6) + 3 = 26
Therefore; the total valence electron is 20
The Lewis dot structure is shown below:

Interpretation:
The Lewis dot structure of
Concept introduction:
Lewis structure represents the valence shell electrons in a compound. It shows the distribution of electrons around each atom in a molecule.
(d)
Explanation of Solution
Phosphorus is a 15th group element which has 5 valence electrons and oxygen is a 16th group element which has 6 valence electron and chlorine is a 17th group element which has 7 valence electrons.
Total number of valence electrons = 5 + 6 + 3(7)
= 5+ 6+ 21
= 32
Therefore; the total valence electron is 32
The Lewis dot structure is shown below:
(e)
Interpretation:
The Lewis dot structure of
Concept introduction:
Lewis structure represents the valence shell electrons in a compound. It shows the distribution of electrons around each atom in a molecule.
(e)
Explanation of Solution
Germanium is a 14th group element which has 4 valence electrons and fluorine is a 17th group element which has 7 valence electrons.
The total valence electron = 4+ 4(7)
= 4 + 28
= 32
Therefore; the total valence electron is 32
The Lewis dot structure is shown below:

As the lead product manager at OrganometALEKS Industries, you are trying to decide if the following reaction will make a molecule with a new C - C bond as its major product: If this reaction will work, draw the major organic product or products you would expect in the drawing area below. If there's more than one major product, you can draw them in any arrangement you like. Be sure you use wedge and dash bonds if necessary, for example to distinguish between major products with different stereochemistry. If the major products of this reaction won't have a new C - C bond, just check the box under the drawing area and leave it blank. Click and drag to start drawing a structure. This reaction will not make a product with a new C - C bond. Х ☐: Carrow_forwardPredict the major products of this organic reaction.
