The correct Answer is:
To determine the bond lengths of carbon in carbon dioxide (CO₂), we need to understand the types of bonds present in the molecule and how they compare to single, double, and triple bonds. ### Step-by-Step Solution: 1. **Identify the Structure of Carbon Dioxide (CO₂)**: - Carbon dioxide consists of one carbon atom (C) and two oxygen atoms (O). - The molecular structure can be represented as O=C=O, indicating that the carbon is double-bonded to each oxygen atom. 2. **Understand Bond Types**: - **Single Bond**: A bond formed by the sharing of one pair of electrons (e.g., C–C or C–O). - **Double Bond**: A bond formed by the sharing of two pairs of electrons (e.g., C=O). - **Triple Bond**: A bond formed by the sharing of three pairs of electrons (e.g., C≡C). 3. **Bond Lengths**: - **Single Bond Length**: Typically longer than double and triple bonds due to less electron density between the atoms. - **Double Bond Length**: Shorter than a single bond due to increased electron density, which pulls the atoms closer together. - **Triple Bond Length**: The shortest bond length because of the highest electron density. 4. **Bond Lengths in CO₂**: - In CO₂, there are no single or triple bonds present; only double bonds exist between carbon and oxygen. - Therefore, we can conclude: - **Single Bond Length**: Not applicable in CO₂. - **Double Bond Length**: The bond length of C=O in CO₂ is approximately 120 pm (picometers). - **Triple Bond Length**: Not applicable in CO₂. 5. **Conclusion**: - The bond lengths in carbon dioxide can be summarized as follows: - Single Bond Length: Not applicable - Double Bond Length: Approximately 120 pm - Triple Bond Length: Not applicable

    Carbon forms a large number of compounds because of its two unique properties formed many have long straight chains of carbon, branched chains of carbon or rings of carbon. In these compounds, carbon atoms may form single, double or triple covalent bonds. Compounds in which the carbon atoms are linked to each other by single bonds are called saturated carbon compounds whereas compounds having at least one carbon-carbon double or triple bond are called unsaturated carbon compounds. Compounds containing only carbon and hydrogen are known as hydrocarbons. Based on the above information, answer the following questions. i. Why does carbon form large number of compounds?
