Expert Solution
Step 1

The expression for calculating the coordination number is shown below:

Coordination number = no. of σ bond + no. of lone pair

Step 2

The structure of given compound is shown below:

Chemistry homework question answer, step 2, image 1

The calculation of coordination number of central atom is shown below:

C.N. of central atom(O) =3 + 1= 4

In electronic geometry; lone pair also considered. So; the electron geometry of H3O+ is tetrahedral.

Step 3

The structure of given compound is shown below:

Chemistry homework question answer, step 3, image 1

The calculation of coordination number of central atom is shown below:

C.N. of central atom(P) =3 + 1= 4

In electronic geometry; lone pair also considered. So; the electron geometry of P(NH2)3 is tetrahedral.
