✍️✍️Organic and inorganic compounds
## Organic Compounds
- Definition: Organic compounds primarily contain carbon atoms, often in combination with hydrogen, oxygen, nitrogen, sulfur, and phosphorus.
- Characteristics:
- Typically covalent bonds.
- Can form long chains or rings.
- Often associated with living organisms.
- Examples:
- Hydrocarbons: Methane (CH₄), Ethylene (C₂H₄)
- Alcohols: Ethanol (C₂H₅OH)
- Carbohydrates: Glucose (C₆H₁₂O₆)
- Proteins: Amino acids (e.g., Glycine, C₂H₅NO₂)
## Inorganic Compounds
- Definition: Inorganic compounds typically do not contain carbon-hydrogen (C-H) bonds. They can include metals, minerals, and various salts.
- Characteristics:
- Often ionic bonds.
- Generally simpler structures compared to organic compounds.
- Found in non-living systems.
- Examples:
- Salts: Sodium chloride (NaCl)
- Oxides: Water (H₂O), Carbon dioxide (CO₂)
- Acids and Bases: Sulfuric acid (H₂SO₄), Sodium hydroxide (NaOH)
- Metals: Iron (Fe), Copper (Cu)

Hello families: We intend to promote our jobs using the application called Linkedin, but according to the rules of the organization, one person cannot have more than one account, so we intend to use other people.
Those of you who have a LinkedIn account with more than 300 connections, say "hi and send me a screenshot of the account's home page".
We will see and then:
Depending on the quality and quantity, we will pay 8$-10$ every week by the ways you choose.
Good Luck!!!
