Per NCERT §4.5.4, the SIGMA (σ) bond and PI (π) bond differ in which way?
Aσ involves d-orbitals only; π involves f-orbitals
Bσ is between metals; π is between non-metals
Cσ is always longer than π
Dσ = end-on (head-on / axial) overlap along internuclear axis; π = sidewise (lateral) overlap of parallel p orbitals
Answer & Solution
Correct answer: D. σ = end-on (head-on / axial) overlap along internuclear axis; π = sidewise (lateral) overlap of parallel p orbitals
Per NCERT §4.5.4, σ = axial overlap (s-s, s-p, p-p); π = sidewise overlap of parallel p-orbitals, two saucer clouds above + below plane.
