Today we are going to learn how to estimate four different chemical formulas based on valence electrons that we can get from the periodic table. Carbon has four valence electrons, which means that there will be four surrounding substituents.
Lets try it!
What is the expected chemical formula of CCl? ?
Carbons four valence electrons gets filled with chlorines, making the chemical formula CCl4
Lets try another one! Remember that Carbon has four valence electrons that make a total of four bonds.
What is the chemical formula for: CH?Cl2
If there are two chlorines, then there must be two hydrogens to satisfy carbons 4 valence electrons. This will make the formula CH2Cl2
