Question

Predict the shapes by matching columns:

Answer 1

(1) According to VSEPR theory, the molecule will have a seesaw geometry $\left(A{X}_{4}E\right)-Te{Cl}_4$ due to 1 lone pair.

(2) $Cl{O}_3^{-};Cl$ has $-5$ oxidation state. As predicted by VSEPR, chlorate anions have trigonal pyramidal structures. But due to lone pair the bond angle is less than $109.5°$.

(3) $Cl{O}_2^{+}$ has angular shape because the one lone pair of electrons around the chlorine atom make the overall shape of $Cl{O}_2^{+}$ to be bent. The bond angle is slightly less than $120°$.

(4) $Cl{O}_3^{+}$ has a trigonal planar geometry with bond angle $120°$ according to the VSEPR geometry.
