The molecular geometry of PF ₃ is ...... .

Options

  1. Atetrahedral
  2. Bpyramidal
  3. Ctrigonal planar
  4. Dsquare planar

Correct answer

B. pyramidal

Step-by-step solution

PF ₃ has four regions of electron density / electron clouds around the central P atom. The regions of electrons make a tetrahedral arrangement with a bond angle of 109.5 . Only three regions of electrons are bonding and one is non-bonding, so the overall shape is trigonal pyramidal. Thus, the correct option (2).
