What are the 5 rules for naming covalent compounds?
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 are the rules in naming ionic and molecular compounds?
When naming binary ionic compounds, name the cation first (specifying the charge, if necessary), then the nonmetal anion (element stem + -ide). Do NOT use prefixes to indicate how many of each element is present; this information is implied in the name of the compound.
What is the first rule of naming compounds?
The IUPAC Systematic Approach to Nomenclature First, it should indicate how the carbon atoms of a given compound are bonded together in a characteristic lattice of chains and rings. Second, it should identify and locate any functional groups present in the compound.
What are the basic rules for writing the name of an ionic compound?
Rule 1. The cation is written first in the name; the anion is written second in the name. Rule 2. When the formula unit contains two or more of the same polyatomic ion, that ion is written in parentheses with the subscript written outside the parentheses.
Which is the correct way to name a molecular compound?
Naming Molecular Compounds 1 Chemical Nomenclature. 2 Rules for Naming Molecular Compounds: Remove the ending of the second element, and add “ide” just like in ionic compounds. 3 Examples of Molecular Compound Names: Naming Compounds – Part 2 – YouTube This video explains how to use a chemical name to write the formula for that compound.
What are the rules for naming chemical compounds?
nomenclatureA set of rules used for forming the names or terms in a particular field of arts or sciences. electronegativeTending to attract electrons within a chemical bond. electropositiveTending to not attract electrons (repel) within a chemical bond.
How to name a compound with more than two elements?
Naming covalent molecular compounds: Left then right, use prefixes. First name the element that is leftmost on the periodic table. Use just the element name. If both elements are in the same column (e.g. sulfur and oxygen), name the lower one first.
