Give the systematic name for each compound. Examples of covalent bonding shown below include hydrogen fluorine carbon dioxide and carbon tetrafluoride.
Carbo coal is a chemical element with the symbol C and atomic number 6.
Carbon tetrafluoride formula. Tetrafluoromethane also known as carbon tetrafluoride or R-14 is the simplest perfluorocarbon C F 4As its IUPAC name indicates tetrafluoromethane is the perfluorinated counterpart to the hydrocarbon methaneIt can also be classified as a haloalkane or halomethaneTetrafluoromethane is a useful refrigerant but also a potent greenhouse gas. It has a very high bond strength due to the. Properties of Carbon tetrafluoride.
It can become a narcotic at high temperatures. It is nonflammable and soluble in chloroform and benzene. It is a potent greenhouse gas.
It has a molar mass of 880043 gmol. It has a boiling point of 1278 C and a melting point of 1836 C. Molecular geometry of CF4.
Carbo coal is a chemical element with the symbol C and atomic number 6. It is nonmetallic and tetravalentmaking four electrons available to form covalent chemical bondsIt belongs to group 14 of the periodic table. Carbon makes up only about 0025 percent of Earths crust.
Three isotopes occur naturally 12 C and 13 C being stable while 14 C is a radionuclide. A binary covalent compound is composed of two different elements usually nonmetals. For example a molecule of chlorine trifluoride ClF 3 contains 1 atom of chlorine and 3 atoms of fluorine.

Let us practice by naming the compound whose molecular formula is CCl 4The name begins with the name of the first elementcarbon. The second element chlorine becomes chloride and we attach the correct numerical prefix tetra- to indicate that the molecule contains four chlorine atomsPutting these pieces together gives the name carbon tetrachloride for this compound.

Since the prefix in front of carbon is tetra- there are 4 carbons. Since the prefix in front of oxide is mono- there is one oxygen. The formula is C 4 O.
Since the prefix in front of phosphours is di there are two phosphorus. Since the prefix in front of sufide is tri- there are 3 sulfurs. The formula is P 2 S 3.
Some examples of writing the formula of a. The formula of the compound often provides a hint as to the skeleton structure. The formula for the chlorate ion for example suggests the following skeleton structure.
The third step assumes that the skeleton structure of the molecule is held together by covalent bonds. The valence electrons are therefore divided into two categories. Bonding electrons and nonbonding electrons.

Examples of covalent bonding shown below include hydrogen fluorine carbon dioxide and carbon tetrafluoride.
These illustrations use a simple Bohr notation with valence electrons designated by colored dots. Note that in the first case both hydrogen atoms achieve a helium-like pair of 1s-electrons by sharing. In the other examples carbon oxygen and fluorine achieve neon-like valence octets.
