Molecular Compounds

Naming Molecular Compounds

• Use the 1st name of the element
• 2 elements end in -ide
• 1 atom usually does not have a prefix. NO---> Nitrogen monoxide
• Hydrogen does not get a prefix

* Also be aware of the Latin prefixes. They are very important!!

Acids and Bases

Terms:

Acid:A solution that has an excess of H- ions. It comes from the Latin word acidus that means "sharp" or "sour". 

Base: A solution that has an excess of OH- ions. Another word for base is alkali

Acids & Bases have different properties...

Classical Names:

• Ferr- Iron
• Cupp-Copper
• Mercur-Mercury
• Stann- Tin
• Aunn- Gold
• Plumb- Lead

Naming acids
 *use the suffix- ic & or the prefix hydro
*Hydrogen appears first in the formula unless it is part of a polyatomic group

ex: sulfuric acid

      hydrochloric acid

• Hydrogen Compounds are acids
• HCl---->Hydrochloric acid

*IUPAC system was the aqeuous hydrogen compound

                                           Acids/ Bases to memorize

Naming Bases

*Use the cation name followed by hydroxide
- Sodium Hydroxide
- Barium Hydroxide

E.g: HI---> Iodic acid
       HBR---> Hydrobromic acid
       HOOCCOOH---> Oxalic acid

Here's a video that nay help you in Naming acids and Bases

            Hydrates

• These crystals contain water inside them which can be released by heating.

        Naming Hydrates

*These easy steps will help you ensure you get Hydrates right

1. Write the name of the chemical formula

2. ADD the prefix & # of water molecules

3. After the prefix add the hydrate

Here are some examples:
