The correct Answer is:
To solve the question regarding which orbitals are involved in hyperconjugation, we can follow these steps: ### Step 1: Understand Hyperconjugation Hyperconjugation is a concept in organic chemistry that refers to the interaction between the electrons in a sigma bond (such as C-H or C-C) and an adjacent empty or partially filled p-orbital or a pi bond. This interaction helps to stabilize the molecule. ### Step 2: Identify the Orbitals Involved In hyperconjugation, the key orbitals involved are: - **Sigma (σ) bonds**: These are formed by the head-on overlap of atomic orbitals (like C-H or C-C bonds). - **Pi (π) bonds**: These are formed by the side-to-side overlap of p-orbitals. ### Step 3: Analyze the Options Given the options, we need to determine which orbital overlaps are relevant to hyperconjugation. The options might typically include: - Sigma bonds - Pi bonds - Non-bonding orbitals - Anti-bonding orbitals ### Step 4: Determine the Correct Answer Since hyperconjugation specifically involves the interaction of sigma bonds with adjacent p-orbitals or pi bonds, the correct answer would be: - **Sigma (σ) and Pi (π) bonds**. Thus, the correct option is **B: Sigma Pi bond**. ### Final Answer The correct answer is **B: Sigma Pi bond**. ---
