Per NCERT §4.6.3, PCl₅ uses what hybridisation, and gives what geometry?
Asp³d; trigonal bipyramidal
Bsp³d²; octahedral
Csp²; trigonal planar
Dsp³; tetrahedral
Answer & Solution
Correct answer: A. sp³d; trigonal bipyramidal
Per NCERT §4.6.3(i), PCl₅ sp³d → trigonal bipyramidal. 3 equatorial (120°) + 2 axial (90°). Axial bonds longer / weaker.
