Which statement is true about organic compounds? 1) Organic compounds always contain carbon. 2) Organic compounds are synthesized only by animal cells. 3) Organic compounds always contain oxygen. 4) Organic compounds can be synthesized only in a laboratory. 5) Organic compounds always contain nitrogen.

Answer:

1) organic compounds always contain carbon

Explanation:

organic compounds are molecules that contain carbon atoms bonded to other elements

Final answer:

The correct statement is 'Organic compounds always contain carbon'. Not all carbon-containing compounds are organic, and organic compounds are not exclusive to animal cells nor do they necessarily contain oxygen. Organic compounds can be formed by living organisms, through geological processes, and in the lab.

Explanation:

The true statement about organic compounds is 'Organic compounds always contain carbon'. This is because organic compounds, both natural and synthetic, are characterized primarily by the presence of carbon as the principal element, which is bonded to hydrogen and other carbon atoms. Carbon possesses the unique ability to form up to four covalent bonds with other atoms, resulting in an enormous variety of possible compounds.

It's important to note that not all carbon-containing compounds are considered organic. For instance, carbonates, cyanides, and simple oxides like CO and CO₂ are not classified as organic. Also, contrary to 'Organic compounds can be synthesized only in a laboratory', organic compounds are not only synthesized anthropogenically but are also formed by living organisms and through geological processes. 'Organic compounds are synthesized only by animal cells' and 'Organic compounds always contain oxygen' are, likewise, incorrect, as organic compounds are not exclusive to animal cells and don't necessarily have to contain oxygen.
