Per NCERT Table 4.7, the shape of SF₄ (5 e⁻ pairs: 4 bp + 1 lp around S) is which?
ASee-saw (distorted tetrahedron from trigonal bipyramidal, with lp in equatorial position)
BTetrahedral
CT-shape
DSquare planar
Answer & Solution
Correct answer: A. See-saw (distorted tetrahedron from trigonal bipyramidal, with lp in equatorial position)
Per NCERT Table 4.7, AB₄E type: SF₄ is see-saw. lp goes equatorial (less repulsion). ClF₃ similarly → T-shape (AB₃E₂).
