Which class of compounds excludes C-C or C-H bonds, including oxides of carbon, carbonates, cyanides, and carbides?

Which class of compounds excludes C-C or C-H bonds, including oxides of carbon, carbonates, cyanides, and carbides?

• A. Organic
• B. Indicator
• C. Inorganic
• D. Buffer region

Answer: (C)

The main idea is that organic chemistry is defined by molecules that contain carbon-hydrogen (C–H) bonds. If a carbon-containing compound lacks C–H bonds, it’s typically placed in inorganic chemistry. That’s why oxides of carbon, carbonates, cyanides, and many carbides are categorized as inorganic—they do not involve C–H bonds. Organic chemistry, by contrast, focuses on carbon compounds with C–H bonds, though there are edge cases and different definitions in use.
