Per NCERT Table 4.6, what is the geometry of a molecule of type AB₅ with NO lone pairs on the central atom (e.g. PCl₅)?
AOctahedral
BTetrahedral
CTrigonal bipyramidal
DSquare pyramidal
Answer & Solution
Correct answer: C. Trigonal bipyramidal
Per NCERT Table 4.6, AB₅ with 0 lp → trigonal bipyramidal (PCl₅). 3 equatorial at 120°, 2 axial at 90°.
