Solution: Predict the ideal bond angle(s) in the chlorite ion:A. 90°      B. 109.5°      C. 120°      D. 180°     E. more than one of the other answers is correct

Problem

Predict the ideal bond angle(s) in the chlorite ion:

A. 90°      B. 109.5°      C. 120°      D. 180°     E. more than one of the other answers is correct

Solution

We’re being asked to draw a predict the ideal bond angle for the chlorite ion (ClO2-)


To do that we would first need to determine the Lewis structure.

We first need to determine the total number of valence electrons present in the molecule:

*each negative charge adds an electron

                 Group            Valence Electrons

O               6A                    2 × 6 e12 e

Cl              7A                     1 × 7 e7 e

Charge     (-1)                                    +1 e 

                        Total:  20 valence e
