An isolated neutral ZBr₄ molecule has four equivalent bonds and zero permanent dipole. It is known independently that all five nuclei are coplanar. Which conventional central-atom valence-shell description is compatible with these facts?
Options:
Answer:
C
Solution:
The independent coplanarity condition excludes the nonpolar tetrahedron. Square-planar AX₄E₂ has four equivalent bond directions whose dipoles cancel. AX₄E is seesaw and generally polar; AX₄E₃ is not T-shaped. Thus the data support C.
