Question

boron trifluoride is used in the electronics industry in processes that grow single crystals of silicon. its molecular formula is bf3, and its condensed formula is also bf3, i.e. it has a central boron atom bonded to three fluorine atoms. what molecular shape does boron trifluoride have, and is it a polar or nonpolar molecule? trigonal pyramidal and polar trigonal pyramidal and nonpolar trigonal planar and polar trigonal planar and nonpolar dont test me yet, i am trying to gain an understanding before attempting to answer this question.

Explanation:

The Lewis - structure of BF₃ shows the central boron atom with three bonding pairs and no lone pairs. According to VSEPR theory, this results in a trigonal planar molecular geometry. The B - F bonds are polar due to the electronegativity difference between B and F, but the symmetry of the trigonal planar shape causes the bond dipoles to cancel out, making the molecule non - polar.

Answer:

trigonal planar and nonpolar
