How To Name Compounds

How To Name Compounds

The video is clearly depicting a clear idea about naming of chemical compounds. It clearly explains the naming of carbon and non carbon compounds, metal and nonmetal compounds.

Hi, I am Donald Sinclair, one of the teachers of Greater London Tutors. Now, I am going to teach you about a few of the topics of chemistry. This is how to name compounds in chemistry.

Naming compounds is very simple. For example, copper chloride. If you know what the symbols are and the elements of periodic table, it is very simple thing to name, copper chloride.

Copper chloride retains copper in chlorine. The only thing you're after, have to remember is that when we see compounds like metal and nonmetal, the nonmetal compounds are given the suffix ‘ide” at the end. Similarly, the next one is aluminium sulphate.

If however oxygen is present, then it is usually given at the end. So for example, aluminium sulphate, it has sulphur at end, so the name sulphate. The “ate” at the end specifies oxygen is present as well.

However nonmetal names at the end of compounds which are a little bit different in the periodic table are oxides, for example, magnesium oxide consisting of magnesium and oxygen. Magnesium oxide means reduction is present. Similarly, sodium hydroxide, the OH means the hydroxide group.

So it is given the name sodium hydroxide. Another handy thing to know is naming conventions for simple organic compounds. To start off, organic compounds is how many carbon atoms the compound contains, starting from the simple methane and adding more carbons ethane, propane, butane and pentane carrying the names which are Greek names based on the number of carbon atoms they have, 6 is hexane, 7 is heptane and 8 is hectane.

The ending of organic compounds tells what type of organic compound it is .The “ane' at end tells us these are alkanes which have single bond between carbon atoms. The other important group is alkenes.

These are exact, the names of alkanes except at the end “enes.” This is because of the double bond between carbon atoms. If these have 3 carbon atoms, it follows propene and 4 atoms butene.

The alcohols are having hydroxide at the end as one of the molecules, so they have at end “anol” like ethanol, butanol and pentanol. Finally, ethanoic acid has two things at the end as molecules a double bond with oxygen and single hydroxide bond, so does ethanoic acid, prupanoic acid and butanoic acid. .
