How do I name covalent compounds given the formula?
How do I name covalent compounds given the formula?
Rules for naming simple covalent compounds:
- Name the non-metal furthest to the left on the periodic table by its elemental name.
- Name the other non-metal by its elemental name and an -ide ending.
- Use the prefixes mono-, di-, tri-…. to indicate the number of that element in the molecule.
What is the pattern for naming covalent compounds?
Place the elements in their proper order. The element farthest to the left in the periodic table is usually named first. If both elements are in the same group, the element closer to the bottom of the column is named first.
What formula represents covalent compounds?
Each covalent compound is represented by a molecular formula, which gives the atomic symbol for each component element, in a prescribed order, accompanied by a subscript indicating the number of atoms of that element in the molecule. The subscript is written only if the number of atoms is greater than 1.
How do you name compounds in formulas?
Naming binary (two-element) molecular compounds is similar to naming simple ionic compounds. The first element in the formula is simply listed using the name of the element. The second element is named by taking the stem of the element name and adding the suffix -ide.
Is HCN a covalent bond?
HCN with ten valence electrons is a molecular bond with a linear-shaped molecule, also known as a covalent bond. Since HCN contains N, which is not directly bonded to hydrogen atoms, it has dipole-dipole forces act between the electron pair of the HCN molecule.
What are examples of covalent compounds?
These are examples of covalent bonds and covalent compounds. Covalent compounds also are known as molecular compounds. Organic compounds, such as carbohydrates, lipids, proteins, and nucleic acids, are all examples of molecular compounds. You can recognize these compounds because they consist of nonmetals bonded to each other.
What are some compound names?
Common Names. Some compounds have been known for so long that a systematic nomenclature cannot compete with well-established common names. Examples of compounds for which common names are used include water (H2O), ammonia (NH3), and methane (CH4).
What are some examples of polar covalent compounds?
There are many different non-metallic elements that can join together in a polar covalent bond, forming such compounds as water, carbon dioxide and hydrochloric acid. Other types of compounds that contain polar covalent bonds include amines and peptides.
What are common chemical compounds?
Chemical compound. The substances mentioned above exemplify the two basic types of chemical compounds: molecular ( covalent) and ionic. Methane and water are composed of molecules; that is, they are molecular compounds. Sodium chloride, on the other hand, contains ions; it is an ionic compound.
