(a)
Interpretation:
TheLewis structureof Acetaldehyde and a formal charge of each atom have to be written.
Concept Introduction:
A Lewis structure is also known as Lewis dot diagrams or electron dot structures. The bond between atoms and lone pairs of electrons that is present in the molecule. Lewis structure represents each atom and their position in structure using the chemical symbol. Excess electrons forms the lone pair are given by pair of dots, and are located next to the atom.
The formula for the formal charge can be written as
(a)
Explanation of Solution
The correct Lewis structure of the Acetaldehyde can be drawn as,
Draw a chart:
The total number of valence electron is
(b)
Interpretation:
The Lewis structure for
Concept Introduction:
Refer Part (a).
(b)
Explanation of Solution
There are three correct possible Lewis structure for
First structure:
Draw a chart:
The total number of valence electron is
Second structure:
Draw a chart:
Third structure:
Draw a chart:
Therefore, the first of these three structures is the best one because the formal charge on atoms in that structure is lesser value
