Similarly, in tetrahedral, the resultant of the dipole moment of 3 bonds can become equal to the dipole moment of the fourth bond. 1) The molecular geometry of the BCl3 molecule is and this molecule is - A) trigonal pyramidal, polar B) trigonal pyramidal, nonpolar C) trigonal planar, polar D) trigonal planar, nonpolar E) trigonal bipyramidal, polar 2) Which one of the following is often easily separated into its components by simple techniques such as filtering or decanting? When comparing the melting point of PCl5 and PCl3, which one has a higher Melting Point? Describe the hybrid orbitals used by the... A. Explanation: In BF3 there are three bond pairs which are shared in between two atoms resulting in the triangular planar structure while in case of NF3 there is sharing of three bond pairs plus one lone pair. The central atom in a trigonal pyramidal is at the apex, whereas the other three atoms are at the base, with a bond angle of about 107 degrees. The answer is Option (a,c). And the entire molecule ensures non zero dipole moment. μ (Polarity) >0. Why nf3 is pyramidal and bf3 is trigonal planar? Three orbitals are arranged around the equator of the molecule with bond angles of 120 o.Two orbitals are arranged along the vertical axis at 90 o from the equatorial orbitals. NCl 3 This molecule is polar because its shape is trigonal pyramidal and has no symmetry. As per VSEPR theory, its geometric shape is trigonal pyramidal and due to differences in the electronegativity between P and F atoms, the P-F bond is polar.
