Interpretation:
The Lewis structure for HCFC-123
Concept introduction:
Lewis structure is also known as Lewis dot structure, which shows the bonding of valence electrons that are present on the atom in the molecule.
In Lewisstructures, bonded electrons are represented by a line and lone pairs are represented by a dot.
In Lewis dot
In Lewis dot symbol, valence electrons are represented by dots.
Dots are placed above and below as well as to the left and right of symbol.
Number of dots is important in Lewis dot symbol but not the order in which the dots are placed around the symbol.
In writing symbol pairing is not done until absolutely necessary.
For metals, the number of dots represents the number of electrons that are lost when the atom forms a cation.
For second period non-metals, the number of unpaired dots is the number of bonds the atom can form.
Atomic ions can also be represented by dot symbols, by simply adding (for anions) and subtracting (for cations) the appropriate number of dots from Lewis dot symbol.
