A pi (π) bond is characterised by:
AStrong overlap, stronger than σ
BMaximum electron density along the internuclear axis
CTwo saucer-like electron clouds above and below the plane of the bonded atoms, formed by sidewise overlap
DFree rotation about the bond axis
Answer & Solution
Correct answer: C. Two saucer-like electron clouds above and below the plane of the bonded atoms, formed by sidewise overlap
A π bond forms when p orbitals overlap **sidewise** (perpendicular to the internuclear axis), giving two electron-density lobes — one above and one below the plane. π bonds are weaker than σ bonds (less overlap) and restrict rotation.
