Description

266. In which molecule - BF3 or NH3 - the value of the dipole moment is greater: a) in BF3; B) in NH3; C) are the dipole moments equal?

Because: 1) the difference in the electronegativity of atoms in the BF3 molecule is greater than in the NH3 molecule; 2) the BF3 molecule has a planar structure, and the NH3 molecule is pyramidal; 3) the nitrogen atom has an unshared pair of electrons, and for the boron atom a free (vacant) valence orbital
