Verified step by step guidance

Understand the definition of an organic compound: Organic compounds are primarily made of carbon atoms bonded to hydrogen atoms, and often include other elements such as oxygen, nitrogen, sulfur, and halogens.

Identify the key structural feature of organic compounds: The presence of carbon-hydrogen (C–H) bonds is a defining characteristic of organic compounds.

Examine the molecular structure of tetrachloroethane (C2H2Cl4): This molecule contains carbon (C), hydrogen (H), and chlorine (Cl) atoms.

Determine which bond in tetrachloroethane indicates its organic nature: The C–H bond is crucial because it signifies the presence of hydrogen directly bonded to carbon, a hallmark of organic chemistry.

Conclude why the C–H bond is the correct answer: The C–H bond is the feature that classifies tetrachloroethane as an organic compound, distinguishing it from inorganic compounds that lack this bond.
