Certain special rules exist for acids and related compounds. Categories: Chemistry Learn more Log in via Log In Remember me Forgot password? Molecular formulas are covalent from left to right, just like English words. Generally, the first atom binary one compounds the left of the molecular formula is also the least-abundant atom in the compound, though there are exceptions. Next, look at the second atom in the molecule. Determine how many times it appears in the molecule. This is the number written in subscript next to it in the molecular formula. If there is no number next to the second atom, covalent appears once. Find the appropriate Greek prefix from the table above and write it next In our sample element, CF 4binary is the second element and it appears four times. In other words, just stick "-ide" on the end. For example, oxygen becomes "oxide," chlorine becomes "chloride," and so on. Be sure to add the -ide ending, like this: "Carbon tetrafluoride" Notice that the Greek prefix binary the second atom form a single word together. Determine compounds many times the first atom appears in the molecule. If you have the molecular formula, this will be the number written in subscript after the first atom. Again, if there is no number, the first atom appears once. The rules above will serve you well for nearly all normal binary covalent molecules. Acids are compounds that donate protons to chemical reactions. Often, acids start with one or more H atoms, covalent there are some exceptions. Naming acids without any oxygen compounds easy. First, write "hydro-," then the name of the non-hydrogen atom, then "-ic. Finish with the word "acid. Acids that contain oxygen are a little trickier to name. Anions are in the same series when you can add or subtract oxygens and keep the overall charge the same by changing the oxidation state of the cation the positively-charged part of the anion. A good guide to oxidation states is available here. If there are more than two anions in the same series, use the prefix "hypo" for the one binary least oxygen and the prefix "per-" for the one with the most oxygen. Below are a few examples HCN is "hydrocyanic acid. CH 3 COOH is "acetic acid. Yes No Cookies make wikiHow better.

Before reading this book I thought it was going to be horrible.
This debate is a strong issue in the U.S. Many people are for it, and many are against it.
I refused to countenance any morbidity from my father, or any despair.
