Question

Is the Cl₂BBCl₂ molecule polar or nonpolar?

a) Polar
b) Nonpolar
c) It depends on the orientation of atoms
d) Can't be determined

Answer 1

Cl₂BBCl₂ is a nonpolar molecule. Correct option is b.

Step-by-step explanation:

A molecule is considered polar if it has a net dipole moment. This occurs when the individual bond dipoles do not cancel each other out due to the molecular shape. Therefore, to determine if Cl₂BBCl₂ is polar or nonpolar, we need to look at its molecular shape and bond dipoles.

Cl₂BBCl₂ has a trigonal bipyramidal molecular shape. The Cl-B bonds are polar due to the difference in electronegativity between Cl (3.16) and B (2.04). However, the bond dipoles cancel each other out symmetrically in this molecular shape, resulting in a nonpolar molecule.

So, the answer is Nonpolar (b).
