This document introduces Marco Antonio Orozco de la Cruz, a chemical engineer and teacher from Guadalajara University who has been teaching chemistry, physics, and mathematics for teens and adults. It provides an overview of binary compounds, including how they are classified and named using both traditional and IUPAC nomenclature. Examples are given of naming acid compounds specifically, such as hydrogen chloride under traditional naming and hydrogen chloride under IUPAC naming. Readers are invited to contact Marco Antonio with any questions.

1. Hi, my name is
Marco Antonio Orozco de la Cruz
Chemical Engineer
Teacher from Guadalajara University for
preparatory level.

2. I've been learning English language at the
PROULEX Institute.
I did the GESE (Graded Examination in Spoken
English) from Trinity College London.

My level is intermediate .

3. • I have been teaching chemistry, physics and
mathematics for teens and adults with an
intermediate level around two years.

4. Inorganic binary compounds
Writing and Naming
Acids
Prof. Marco Antonio Orozco de la Cruz

5. Binary Compounds
• We have to know that a binary compound is:
• A substance combine by two elements e.g.:

6. • And the compounds are classified in:
A) Hydracids Acids
B) Oxides
C) Anhydrides
D)Salts

7. Kinds of Nomenclature
• Traditional
• IUPAC

8. • Now, we´ll show how to name some acids:
• First we will identify an acid compound:
Its name is derived by combination of the anion
(“Non Metal Element”) , that we write on the
right side of the formula and the cation
(“Hydrogen”) we’ll write on the left side.

9. • Next we have some examples:
• HCl
• HI
• H2S

10. Naming by Traditional
• First: we are going to write the name from the
Non Metal and then we add
“–hydric”
• Second: write “acid”
• Example: HCl Chlorhydric acid

11. • Naming by IUPAC
We should use the next numerical prefixes
1: Mono
2: Di
3: Tri
4: Tetra
5: Penta
6: Hexa

12. • Now we’ll name some acid compounds
First, we are going to write the word “hydrogen”
Second, we are going to add the name from
“Non metal element”
Third, finally we add -ide

13. • Examples:
• HCl – hydrogen chloride
• HI – hydrogen iodide
• H2S – dihydrogen sulfide
