The correct Answer is:
To identify the molecule that exhibits sideways overlapping of atomic orbitals, we can follow these steps: ### Step 1: Understand Sideways Overlapping Sideways overlapping of atomic orbitals typically occurs with p orbitals. This can happen in two ways: - **PP overlapping**: where two p orbitals overlap sideways. - **PD overlapping**: where a p orbital overlaps with a d orbital. ### Step 2: Analyze the Given Molecules We have the following molecules to analyze: 1. **CH₄ (Methane)** 2. **CO₂ (Carbon Dioxide)** 3. **NH₃ (Ammonia)** 4. **H₂O (Water)** ### Step 3: Determine the Hybridization and Overlapping in Each Molecule - **CH₄ (Methane)**: - Hybridization: sp³ - Overlapping: Involves sp³ hybrid orbitals, which do not allow for sideways overlapping. - Conclusion: No sideways overlapping. - **CO₂ (Carbon Dioxide)**: - Hybridization: sp - Overlapping: The carbon atom has p orbitals that can overlap sideways with the p orbitals of the oxygen atoms. - Conclusion: Sideways overlapping is possible. - **NH₃ (Ammonia)**: - Hybridization: sp³ - Overlapping: Involves sp³ hybrid orbitals, which do not allow for sideways overlapping. - Conclusion: No sideways overlapping. - **H₂O (Water)**: - Hybridization: sp³ - Overlapping: Involves sp³ hybrid orbitals, which do not allow for sideways overlapping. - Conclusion: No sideways overlapping. ### Step 4: Identify the Correct Answer From the analysis, the only molecule that exhibits sideways overlapping of atomic orbitals is **CO₂ (Carbon Dioxide)**. ### Final Answer The molecule having sideways overlapping of atomic orbitals is **CO₂ (Carbon Dioxide)**. ---

  • Sideways overlap of p-p orbitals forms

    A
    sigma bond
    B
    pi bond
    C
    coordinate bond
    D
    H bond

  • A covalent bond will be formed by the overlapping of atomic orbitals having single electron of opposite spin, according to the overlapping of atomic orbitals the covalent bond may be of two types : (i) Sigma bond (sigma) " " (ii) Pi bond (pi) Sigma bond is stronger bond than the Pi-bond. If atomic orbitals overlap about the nuclear axis then sigma bond is formed but when atomic orbitals overlap sideway then Pi-bond is formed. Compound having maximum bond angle is :
