Question

question 13
how do organic compounds differ from inorganic compounds?
inorganic compounds never contain carbon, whereas organic compounds always contain carbon.
organic compounds are always acidic, while inorganic compounds are always basic
organic compounds consist of carbon atoms joined by covalent bonds, while inorganic compounds lack carbon - carbon bonds.
organic compounds are natural, while inorganic compounds are artificially synthesized.
inorganic compounds always only consist of two atoms.

Explanation:

• Organic compounds are characterized by carbon - carbon covalent bonds. Inorganic compounds generally lack such carbon - carbon bonds.
• Inorganic compounds can contain carbon (e.g., carbonates like \(CaCO_3\)), so the first option is wrong.
• Organic compounds are not always acidic (e.g., glucose \(C_6H_{12}O_6\)) and inorganic compounds are not always basic (e.g., \(HCl\)), so the second option is wrong.
• Organic compounds can be synthetic (e.g., synthetic plastics are organic) and inorganic compounds can be natural (e.g., minerals like \(NaCl\) in nature), so the fourth option is wrong.
• Inorganic compounds can have more than two atoms (e.g., \(Na_2SO_4\) has many atoms), so the fifth option is wrong.

Answer:

Organic compounds consist of carbon atoms joined by covalent bonds, while inorganic compounds lack carbon - carbon bonds.
