A) Lewis dot structure, bent, polar bonds, polar molecule
B) Lewis dot structure, bent, nonpolar bonds, nonpolar molecule
C) Lewis dot structure, linear, polar bonds, polar molecule
D) Lewis dot structure, linear, nonpolar bonds, nonpolar molecule

Answer 1

The molecule CBr2F2 has a bent structure with polar bonds and is a polar molecule, thus the correct answer is Option A.

Step-by-step explanation:

The correct answer to the question regarding the Lewis dot structure, shape, polarity of bonds, and overall polarity of CBr2F2 is: Option A - Lewis dot structure, bent, polar bonds, polar molecule.

The Lewis dot structure for CBr2F2 would show carbon in the center with four electron pairs bonding it to two bromine atoms and two fluorine atoms. By applying VSEPR theory, we can determine the molecule's shape based on the electron pair geometry around the carbon atom. In this case, the electron pair geometry is tetrahedral giving rise to a molecular structure that is bent due to the different atoms attached to the central atom.

Since the attached atoms are bromine and fluorine, which have different electronegativities, the bonds are indeed polar bonds. The molecular structure is asymmetric, which prevents the bond dipoles from canceling out. Consequently, CBr2F2 has a net dipole moment, classifying it as a polar molecule.
