The correct Answer is:
To determine which of the given options represents the hybridization pattern `sp², sp², sp, sp` from left to right, we will analyze the hybridization of the carbon atoms in each option systematically. ### Step-by-Step Solution: 1. **Understanding Hybridization**: - `sp²` hybridization occurs in carbon atoms that form three sigma bonds (e.g., in alkenes). - `sp` hybridization occurs in carbon atoms that form two sigma bonds and two pi bonds (e.g., in alkynes). 2. **Analyzing the Options**: - We will evaluate each option to identify the hybridization of the carbon atoms from left to right. 3. **Option 1**: - Structure: H₂C=CH≡C-H - Analyzing: - The first carbon (H₂C) is bonded to two hydrogens and one carbon (double bond) → 3 sigma bonds → `sp²`. - The second carbon (CH) is bonded to one hydrogen and one carbon (double bond) and one carbon (triple bond) → 3 sigma bonds → `sp²`. - The third carbon (C≡C) is bonded to one carbon (triple bond) and one carbon (double bond) → 2 sigma bonds → `sp`. - The last carbon (C) is bonded to one hydrogen and one carbon (triple bond) → 2 sigma bonds → `sp`. - Conclusion: This option gives us `sp², sp², sp, sp`. 4. **Option 2**: - Structure: H₂C=CH-CH=CH₂ - Analyzing: - The first carbon (H₂C) is `sp²`. - The second carbon (CH) is `sp²`. - The third carbon (CH) is `sp²`. - The last carbon (H₂C) is `sp²`. - Conclusion: All carbons are `sp²`, so this option is incorrect. 5. **Option 3**: - Structure: H₂C=CH-CH₂-CH₃ - Analyzing: - The first carbon (H₂C) is `sp²`. - The second carbon (CH) is `sp²`. - The third carbon (CH₂) is `sp³`. - The last carbon (CH₃) is `sp³`. - Conclusion: This option does not match the required hybridization. 6. **Option 4**: - Structure: H₂C=CH₂ - Analyzing: - Both carbons are `sp²`. - Conclusion: This option is incorrect as it does not match the hybridization pattern. ### Final Answer: The correct option that represents the hybridization `sp², sp², sp, sp` from left to right is **Option 1**.
