Question

Draw the electron dot formula for the hypochlorite ion, clo-. how many nonbonding electron pairs are in a hypochlorite ion? 1 6 7 2 none of the above

Answer 1

Answer:
            There are 6 nonbonding electron pairs are in a hypochlorite ion.

Explanation:
                   Lewis structure of ClO⁻ is drawn as,

1) Add valence electrons of both elements along with additional one electron present in the form of negative charge on molecular ion, so,

Valence e⁻ of Cl           =   7

Valence e⁻ of O            =   6

e⁻ for negative charge  =  1
                                      ------------
Total e⁻                             14

2) Draw both elements and connect them by single bond, and subtract 2 electrons from total valence electrons,
So,
                                         14  -  2  =  12

Now distribute remaining 12 electrons on both element in order to complete their octet.

Result:
           Each element gets three lone pair of electrons which are not involed in bonding. Therefore, overall 6 nonbonding electron pairs are present on ClO⁻ ion.
