Molecular geometry xo © Pë il Trigonal Pyramidal Because of lone pair bond angle will be lan than 109150 Total valence electron 226 See-Saw Structure Total valence electron= 34 is the molecule Polar ? 8+ 8 - xH 18 40 R E P Bra T: Re This molecules will be Polar. Two-anial & P_ R'bond anoment will cancel each other. But others are not, so the molecule will have resultant dipolemoment. So it. will be polar.
