Question
How do you know that all of these carbons (referring to the carbons in the figure in Model - Alkane Nomenclature) satisfy the octet rule?
The number of bonds plus the number of electrons per bond is equal to eight.
The number of bonds times (multipled by) the numer of electrons per bond is equal to eight.
The number of electrons per bond is eight.
The number of bonds is eight.
a.The number of bonds plus the number of electrons per bond is equal to eight.
b.The number of bonds times (multipled by) the numer of electrons per bond is equal to eight.
c.The number of electrons per bond is eight.
d.The number of bonds is eight.
Explanation / Answer
Answer) b
The number of bonds times (multipled by) the numer of electrons per bond is equal to eight.
Let us prove this by taking an example.
In CH3-CH3 each carbon is surrounded by 4 bonds
>C < .
Total number of bonds = 4
Number of electrons per bond = 2
Total number of bonds X Number of electrons per bond = 4 × 2 = 8
Thus octet rule is satsfied.
