Which of the following overlaps is positive (gives bonding)?
As with the positive lobe of p (head-on)
Bs with s of opposite phase
Cp_x with p_y at 90° (perpendicular)
Ds with the negative lobe of p
Answer & Solution
Correct answer: A. s with the positive lobe of p (head-on)
Positive overlap requires orbitals with the **same phase (sign)** to overlap along the bond axis. s with the positive lobe of p, head-on, is the textbook example. Opposite-phase overlap is negative; perpendicular orbitals give zero overlap.
