The correct Answer is:
To solve the question regarding the number of sigma and pi bonds in a molecule, we will analyze the given information step by step. ### Step-by-Step Solution: 1. **Understanding the Given Information**: - We have the following bonds: - Sigma (C-C) = 4 - Sigma (C-H) = 6 - Pi (C=C) = 1 - Pi (C-C) = 2 2. **Analyzing Sigma C-C Bonds**: - Sigma C-C bonds indicate the number of single bonds between carbon atoms. - Given that there are 4 sigma C-C bonds, we can infer that there are 4 carbon atoms involved in these bonds. 3. **Analyzing Sigma C-H Bonds**: - Sigma C-H bonds indicate the number of single bonds between carbon and hydrogen atoms. - With 6 sigma C-H bonds, we can conclude that there are 6 hydrogen atoms bonded to the carbon atoms. 4. **Analyzing Pi C=C Bonds**: - The presence of 1 pi bond (C=C) suggests that there is one double bond between two carbon atoms. 5. **Analyzing Pi C-C Bonds**: - The presence of 2 pi bonds (C-C) suggests that there is a triple bond between two carbon atoms (since a triple bond consists of 1 sigma and 2 pi bonds). 6. **Constructing the Molecule**: - Now, we can visualize the structure: - We have 4 carbon atoms, with one double bond and one triple bond. - The remaining carbon atoms will be connected to hydrogen atoms to satisfy the valency of carbon (which is 4). - This configuration suggests a structure that could be similar to propyne (C3H4) with an additional carbon atom. 7. **Identifying the Correct Option**: - Based on the analysis, we can check the options provided in the question to see which one matches the configuration of 4 sigma C-C bonds, 6 sigma C-H bonds, 1 pi C=C bond, and 2 pi C-C bonds. - After checking the options, we find that **Option 1** satisfies all the conditions. ### Conclusion: The correct option that matches the given number of sigma and pi bonds is **Option 1**.
